This function Cast(Floor(Cast(GetDate() As Float)) As DateTime) returns a datetime datatype with the time portion removed and could be used as so.

Select
*
Table1
Where
Cast(Floor(Cast(Column_DateTime As Float)) As DateTime) = '14-AUG-2008'

or

DECLARE  @p_date DATETIME
SET      @p_date = Cast('14 AUG 2008' as DateTime)

SELECT   *
FROM     table1
WHERE    Cast(Floor(Cast(column_datetime As Float)) As DateTime) = @p_date

DATEADD is the way to go with this

See the W3Schools tutorial: http://www.w3schools.com/sql/func_dateadd.asp

Published by Microsoft in Standard Date and Time Format Strings:

dataGrid.Columns[2].DefaultCellStyle.Format = "d"; // Short date

That should format the date according to the person's location settings.

This is part of Microsoft's larger collection of Formatting Types in .NET.

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

Also available using one of the serializer settings overloads:

var json = JsonConvert.SerializeObject(someObject, new JsonSerializerSettings() { DateFormatString = "yyyy-MM-ddThh:mm:ssZ" });

Or

var json = JsonConvert.SerializeObject(someObject, Formatting.Indented, new JsonSerializerSettings() { DateFormatString = "yyyy-MM-ddThh:mm:ssZ" });

Overloads taking a Type are also available.

Although you can not set the default date format for a single database, you can change the default language for a login which is used to access this database:

ALTER LOGIN your_login WITH DEFAULT_LANGUAGE=British

In some cases it helps.

Not really an answer to your question as asked, but thought I'd chip in about your general objective.

There already is a method to generate random file names in .NET.

See System.Path.GetTempFileName and GetRandomFileName.

Alternatively, it is a common practice to use a GUID to name random files.

What you exactly wan't to do ?. To change Datatype of column you can simple use alter command as

ALTER TABLE table_name ALTER COLUMN LoginDate DateTime;

But remember there should valid Date only in this column however data-type is nvarchar.

If you wan't to convert data type while fetching data then you can use CONVERT function as,

CONVERT(data_type(length),expression,style)

eg:

SELECT CONVERT(DateTime, loginDate, 6)

This will return 29 AUG 13. For details about CONVERT function you can visit ,

http://www.w3schools.com/sql/func_convert.asp.

Remember, Always use DataTime data type for DateTime column.

Thank You

Approach: 1

Given original string format: 2019/03/04 00:08:48

you can use

updated_df = df['timestamp'].astype('datetime64[ns]')

The result will be in this datetime format: 2019-03-04 00:08:48

Approach: 2

updated_df = df.astype({'timestamp':'datetime64[ns]'})

using C# 6.0

$"Date-{DateTime.Now:yyyyMMddHHmmss}"

 // Get calendar set to the current date and time
Calendar cal = Calendar.getInstance();

// Set time of calendar to 18:00
cal.set(Calendar.HOUR_OF_DAY, 18);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

// Check if current time is after 18:00 today
boolean afterSix = Calendar.getInstance().after(cal);

if (afterSix) {
    System.out.println("Go home, it's after 6 PM!");
}
else {
    System.out.println("Hello!");
}

well, thought I should mention a solution I came across through some trying. Discovered whilst fixing a defect of someone comparing dates as strings.

new Date(Date.parse('01-01-1970 01:03:44'))

If you're happy to require 'active_support/core_ext', then you can use

DateTime.now.midnight # => Sat, 19 Nov 2011 00:00:00 -0800

Time for the modern answer.

java.time and ThreeTenABP

    DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("d/M/u");
    String validUntil = "1/1/1990";
    LocalDate validDate = LocalDate.parse(validUntil, dateFormatter);
    LocalDate currentDate = LocalDate.now(ZoneId.of("Pacific/Efate"));
    if (currentDate.isAfter(validDate)) {
        System.out.println("Catalog is outdated");
    }

When I ran this code just now, the output was:

Catalog is outdated

Since it is never the same date in all times zones, give explicit time zone to LocalDate.now. If you want the catalog to expire at the same time in all time zones, you may give ZoneOffset.UTC as long as you inform you users that you are using UTC.

I am using java.time, the modern Java date and time API. The date-time classes that you used, Calendar, SimpleDateFormat and Date, are all poorly designed and fortunately long outdated. Also despite the name a Date doesn’t represent a date, but a point in time. One consequence of this is: even though today is February 15, 2019, a newly created Date object is already after (so not equal to) a Date object from parsing 15/02/2019. This confuses some. Contrary to this the modern LocalDate is a date without time of day (and without time zone), so two LocalDates representing today’s date will always be equal.

Question: Can I use java.time on Android?

Yes, java.time works nicely on older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

PRINT DATEDIFF(second,'2010-01-22 15:29:55.090','2010-01-22 15:30:09.153')

Take a look at the facilities provided by the time module

You have several conversion functions there.

Edit: see the datetime module for more OOP-like solutions. The time library linked above is kinda imperative.

date = datetime.datetime(2003,8,1,12,4,5)
for i in range(5): 
    date += datetime.timedelta(days=1)
    print(date) 

For .NET > 4.0 you can use

TimeSpan time = TimeSpan.FromSeconds(seconds);

//here backslash is must to tell that colon is
//not the part of format, it just a character that we want in output
string str = time .ToString(@"hh\:mm\:ss\:fff");

or if you want date time format then you can also do this

TimeSpan time = TimeSpan.FromSeconds(seconds);
DateTime dateTime = DateTime.Today.Add(time);
string displayTime = dateTime.ToString("hh:mm:tt");

For more you can check Custom TimeSpan Format Strings

I had to face this problem, too. Unfortunately, none of the answers (here and in dozens of other pages) has been satisfactory to me, as I still cannot reach dates beyond the year 2038 due to 32 bit integer casts somewhere.

A solution that did work for me in the end was to use float variables, so I could have at least a max date of 2262-04-11T23:47:16.854775849. Still, this doesn't cover the entire datetime domain, but it is sufficient for my needs and may help others encountering the same problem.

-- date variables
declare @ts bigint; -- 64 bit time stamp, 100ns precision
declare @d datetime2(7) = GETUTCDATE(); -- 'now'
-- select @d = '2262-04-11T23:47:16.854775849'; -- this would be the max date

-- constants:
declare @epoch datetime2(7) = cast('1970-01-01T00:00:00' as datetime2(7));
declare @epochdiff int = 25567; -- = days between 1900-01-01 and 1970-01-01
declare @ticksofday bigint = 864000000000; -- = (24*60*60*1000*1000*10)

-- helper variables:
declare @datepart float;
declare @timepart float;
declare @restored datetime2(7);

-- algorithm:
select @ts = DATEDIFF_BIG(NANOSECOND, @epoch, @d) / 100; -- 'now' in ticks according to unix epoch
select @timepart = (@ts % @ticksofday) / @ticksofday; -- extract time part and scale it to fractional part (i. e. 1 hour is 1/24th of a day)
select @datepart = (@ts - @timepart) / @ticksofday; -- extract date part and scale it to fractional part
select @restored = cast(@epochdiff + @datepart + @timepart as datetime); -- rebuild parts to a datetime value

-- query original datetime, intermediate timestamp and restored datetime for comparison
select
  @d original,
  @ts unix64,
  @restored restored
;

-- example result for max date:
-- +-----------------------------+-------------------+-----------------------------+
-- | original                    | unix64            | restored                    |
-- +-----------------------------+-------------------+-----------------------------+
-- | 2262-04-11 23:47:16.8547758 | 92233720368547758 | 2262-04-11 23:47:16.8533333 |
-- +-----------------------------+-------------------+-----------------------------+

There are some points to consider:

• 100ns precision is the requirement in my case, however this seems to be the standard resolution for 64 bit unix timestamps. If you use any other resolution, you have to adjust @ticksofday and the first line of the algorithm accordingly.
• I'm using other systems that have their problems with time zones etc. and I found the best solution for me would be always using UTC. For your needs, this may differ.
• 1900-01-01 is the origin date for datetime2, just as is the epoch 1970-01-01 for unix timestamps.
• floats helped me to solve the year-2038-problem and integer overflows and such, but keep in mind that floating point numbers are not very performant and may slow down processing of a big amount of timestamps. Also, floats may lead to loss of precision due to roundoff errors, as you can see in the comparison of the example results for the max date above (here, the error is about 1.4425ms).
• In the last line of the algorithm there is a cast to datetime. Unfortunately, there is no explicit cast from numeric values to datetime2 allowed, but it is allowed to cast numerics to datetime explicitly and this, in turn, is cast implicitly to datetime2. This may be correct, for now, but may change in future versions of SQL Server: Either there will be a dateadd_big() function or the explicit cast to datetime2 will be allowed or the explicit cast to datetime will be disallowed, so this may either break or there may come an easier way some day.

The built-in functions work well with Pandas Dataframes.

I know this might seem to be extremely late.. however it may help someone out there

I wanted to get the AM PM part of the date, so I used what Andy advised:

dateTime.ToString("tt");

I used that part to construct a Path to save my files.. I built my assumptions that I will get either AM or PM and nothing else !!

however when I used a PC that its culture is not English ..( in my case ARABIC) .. my application failed becase the format "tt" returned something new not AM nor PM (? or ?)..

So the fix to this was to ignore the culture by adding the second argument as follow:

dateTime.ToString("tt", CultureInfo.InvariantCulture);

.. of course u have to add : using System.Globalization; on top of ur file I hope that will help someone :)

MySQL stores DATETIME without timezone information. Let's say you store '2019-01-01 20:00:00' into a DATETIME field, when you retrieve that value you're expected to know what timezone it belongs to.

So in your case, when you store a value into a DATETIME field, make sure it is Tanzania time. Then when you get it out, it will be Tanzania time. Yay!

Now, the hairy question is: When I do an INSERT/UPDATE, how do I make sure the value is Tanzania time? Two cases:

1. You do INSERT INTO table (dateCreated) VALUES (CURRENT_TIMESTAMP or NOW()).

2. You do INSERT INTO table (dateCreated) VALUES (?), and specify the current time from your application code.

CASE #1

MySQL will take the current time, let's say that is '2019-01-01 20:00:00' Tanzania time. Then MySQL will convert it to UTC, which comes out to '2019-01-01 17:00:00', and store that value into the field.

So how do you get the Tanzania time, which is '20:00:00', to store into the field? It's not possible. Your code will need to expect UTC time when reading from this field.

CASE #2

It depends on what type of value you pass as ?. If you pass the string '2019-01-01 20:00:00', then good for you, that's exactly what will be stored to the DB. If you pass a Date object of some kind, then it'll depend on how the db driver interprets that Date object, and ultimate what 'YYYY-MM-DD HH:mm:ss' string it provides to MySQL for storage. The db driver's documentation should tell you.

Comparing dates in JavaScript is quite easy... JavaScript has built-in comparison system for dates which makes it so easy to do the comparison...

Just follow these steps for comparing 2 dates value, for example you have 2 inputs which each has a Date value in String and you to compare them...

1. you have 2 string values you get from an input and you'd like to compare them, they are as below:

var date1 = '01/12/2018';
var date2 = '12/12/2018';

2. They need to be Date Object to be compared as date values, so simply convert them to date, using new Date(), I just re-assign them for simplicity of explanation, but you can do it anyway you like:

date1 = new Date(date1);
date2 = new Date(date2);

3. Now simply compare them, using the > < >= <=

date1 > date2;  //false
date1 < date2;  //true
date1 >= date2; //false
date1 <= date2; //true

You need to use DateTime.ParseExact with format "dd/MM/yyyy"

DateTime dt=DateTime.ParseExact("24/01/2013", "dd/MM/yyyy", CultureInfo.InvariantCulture);

Its safer if you use d/M/yyyy for the format, since that will handle both single digit and double digits day/month. But that really depends if you are expecting single/double digit values.

Your date format day/Month/Year might be an acceptable date format for some cultures. For example for Canadian Culture en-CA DateTime.Parse would work like:

DateTime dt = DateTime.Parse("24/01/2013", new CultureInfo("en-CA"));

Or

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("en-CA");
DateTime dt = DateTime.Parse("24/01/2013"); //uses the current Thread's culture

Both the above lines would work because the the string's format is acceptable for en-CA culture. Since you are not supplying any culture to your DateTime.Parse call, your current culture is used for parsing which doesn't support the date format. Read more about it at DateTime.Parse.

Another method for parsing is using DateTime.TryParseExact

DateTime dt;
if (DateTime.TryParseExact("24/01/2013", 
                            "d/M/yyyy", 
                            CultureInfo.InvariantCulture, 
                            DateTimeStyles.None,
    out dt))
{
    //valid date
}
else
{
    //invalid date
}

The TryParse group of methods in .Net framework doesn't throw exception on invalid values, instead they return a bool value indicating success or failure in parsing.

Notice that I have used single d and M for day and month respectively. Single d and M works for both single/double digits day and month. So for the format d/M/yyyy valid values could be:

• "24/01/2013"
• "24/1/2013"
• "4/12/2013" //4 December 2013
• "04/12/2013"

For further reading you should see: Custom Date and Time Format Strings

see my answer here:

How can I get the current date and time in UTC or GMT in Java?

I've fully tested it by changing the timezones on the emulator

You can achieve that using DATE_FORMAT() (click the link for more other formats)

SELECT DATE_FORMAT(colName, '%Y-%m-%d') DATEONLY, 
       DATE_FORMAT(colName,'%H:%i:%s') TIMEONLY

SQLFiddle Demo

You can always use strtotime to minus the number of days from the current date:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', date('Y-m-d', strtotime("-30 days"))
           ->get();

You are probably looking for the DATEDIFF function.

DATEDIFF ( datepart , startdate , enddate )

Where you code might look like this:

DATEDIFF ( hh , startdate , enddate )

You are not creating datetime index properly,

format = '%Y-%m-%d %H:%M:%S'
df['Datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'], format=format)
df = df.set_index(pd.DatetimeIndex(df['Datetime']))

convert string to datetime object

from datetime import datetime
s = "2016-03-26T09:25:55.000Z"
f = "%Y-%m-%dT%H:%M:%S.%fZ"
out = datetime.strptime(s, f)
print(out)
output:
2016-03-26 09:25:55

For current date just use UNIX_TIMESTAMP() in your MySQL query.

One can use the getmonth and getday methods to get only the date.

Here I attach my solution:

var fullDate = new Date(); console.log(fullDate);_x000D_
var twoDigitMonth = fullDate.getMonth() + "";_x000D_
if (twoDigitMonth.length == 1)_x000D_
    twoDigitMonth = "0" + twoDigitMonth;_x000D_
var twoDigitDate = fullDate.getDate() + "";_x000D_
if (twoDigitDate.length == 1)_x000D_
    twoDigitDate = "0" + twoDigitDate;_x000D_
var currentDate = twoDigitDate + "/" + twoDigitMonth + "/" + fullDate.getFullYear(); console.log(currentDate);

Try adding a datetime.datetime to a datetime.timedelta. If you only want the time portion, you can call the time() method on the resultant datetime.datetime object to get it.

You'll need two slightly different conversions.

To convert from Time to DateTime you can amend the Time class as follows:

require 'date'
class Time
  def to_datetime
    # Convert seconds + microseconds into a fractional number of seconds
    seconds = sec + Rational(usec, 10**6)

    # Convert a UTC offset measured in minutes to one measured in a
    # fraction of a day.
    offset = Rational(utc_offset, 60 * 60 * 24)
    DateTime.new(year, month, day, hour, min, seconds, offset)
  end
end

Similar adjustments to Date will let you convert DateTime to Time .

class Date
  def to_gm_time
    to_time(new_offset, :gm)
  end

  def to_local_time
    to_time(new_offset(DateTime.now.offset-offset), :local)
  end

  private
  def to_time(dest, method)
    #Convert a fraction of a day to a number of microseconds
    usec = (dest.sec_fraction * 60 * 60 * 24 * (10**6)).to_i
    Time.send(method, dest.year, dest.month, dest.day, dest.hour, dest.min,
              dest.sec, usec)
  end
end

Note that you have to choose between local time and GM/UTC time.

Both the above code snippets are taken from O'Reilly's Ruby Cookbook. Their code reuse policy permits this.

Import moment js:

var fulldate = new Date(1370001284000);
var converted_date = moment(fulldate).format(");

The easiest way to check if given date is valid probably converting it to unixtime using strtotime, formatting it to the given date's format, then comparing it:

function isValidDate($date) { return date('Y-m-d', strtotime($date)) === $date; }

Of course you can use regular expression to check for validness, but it will be limited to given format, every time you will have to edit it to satisfy another formats, and also it will be more than required. Built-in functions is the best way (in most cases) to achieve jobs.

import datetime
a = datetime.datetime.today().year

or even (as Lennart suggested)

a = datetime.datetime.now().year

or even

a = datetime.date.today().year

They should have the same time, the update is supposed to be atomic, meaning that whatever how long it takes to perform, the action is supposed to occurs as if all was done at the same time.

If you're experiencing a different behaviour, it's time to change for another DBMS.

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

This worked for me for a format like YYYY.MM.DD-HH.MM.SS.fff. Attempting to make this code capable of accepting any string format will be like reinventing the wheel (i.e. there are functions for all this in Boost.

std::chrono::system_clock::time_point string_to_time_point(const std::string &str)
{
    using namespace std;
    using namespace std::chrono;

    int yyyy, mm, dd, HH, MM, SS, fff;

    char scanf_format[] = "%4d.%2d.%2d-%2d.%2d.%2d.%3d";

    sscanf(str.c_str(), scanf_format, &yyyy, &mm, &dd, &HH, &MM, &SS, &fff);

    tm ttm = tm();
    ttm.tm_year = yyyy - 1900; // Year since 1900
    ttm.tm_mon = mm - 1; // Month since January 
    ttm.tm_mday = dd; // Day of the month [1-31]
    ttm.tm_hour = HH; // Hour of the day [00-23]
    ttm.tm_min = MM;
    ttm.tm_sec = SS;

    time_t ttime_t = mktime(&ttm);

    system_clock::time_point time_point_result = std::chrono::system_clock::from_time_t(ttime_t);

    time_point_result += std::chrono::milliseconds(fff);
    return time_point_result;
}

std::string time_point_to_string(std::chrono::system_clock::time_point &tp)
{
    using namespace std;
    using namespace std::chrono;

    auto ttime_t = system_clock::to_time_t(tp);
    auto tp_sec = system_clock::from_time_t(ttime_t);
    milliseconds ms = duration_cast<milliseconds>(tp - tp_sec);

    std::tm * ttm = localtime(&ttime_t);

    char date_time_format[] = "%Y.%m.%d-%H.%M.%S";

    char time_str[] = "yyyy.mm.dd.HH-MM.SS.fff";

    strftime(time_str, strlen(time_str), date_time_format, ttm);

    string result(time_str);
    result.append(".");
    result.append(to_string(ms.count()));

    return result;
}

I know the topic is quite old, but such tools are always handy. I've used the resources above and created a version of NtpClient which allows asynchronously to acquire accurate time, instead of event based.

        //**UTC** time
        DateTime networkDateTime = (new DateTime(1900, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc)).AddMilliseconds((long)milliseconds);
        return networkDateTime;

                       ((x & 0x00ff0000) >> 8) +
                       ((x & 0xff000000) >> 24));
    }
}

Usage:

var ntp = new NtpClient();
var accurateTime = await ntp.GetNetworkTimeAsync(TimeSpan.FromSeconds(10));

Expanding on retrography's answer..: I had this same problem even when using LocalDate and not LocalDateTime. The issue was that I had created my DateTimeFormatter using .withResolverStyle(ResolverStyle.STRICT);, so I had to use date pattern uuuuMMdd instead of yyyyMMdd (i.e. "year" instead of "year-of-era")!

DateTimeFormatter formatter = new DateTimeFormatterBuilder()
  .parseStrict()
  .appendPattern("uuuuMMdd")
  .toFormatter()
  .withResolverStyle(ResolverStyle.STRICT);
LocalDate dt = LocalDate.parse("20140218", formatter);

(This solution was originally a comment to retrography's answer, but I was encouraged to post it as a stand-alone answer because it apparently works really well for many people.)

Another nifty way is:

DATEADD(dd, 0, DATEDIFF(dd, 0, [YourDate]))

Which gets the number of days from DAY 0 to YourDate and the adds it to DAY 0 to set the baseline again. This method (or "derivatives" hereof) can be used for a bunch of other date manipulation.

Edit - other date calculations:

First Day of Month:

DATEADD(mm, DATEDIFF(mm, 0, getdate()), 0)

First Day of the Year:

DATEADD(yy, DATEDIFF(yy, 0, getdate()), 0)

First Day of the Quarter:

DATEADD(qq, DATEDIFF(qq, 0, getdate()), 0)

Last Day of Prior Month:

DATEADD(ms, -3, DATEADD(mm, DATEDIFF(mm, 0, getdate()), 0))

Last Day of Current Month:

DATEADD(ms, -3, DATEADD(mm, DATEDIFF(m, 0, getdate()) + 1, 0))

Last Day of Current Year:

DATEADD(ms, -3, DATEADD(yy, DATEDIFF(yy, 0, getdate()) + 1, 0))

First Monday of the Month:

DATEADD(wk, DATEDIFF(wk, 0, DATEADD(dd, 6 - DATEPART(day, getdate()), getdate())), 0)        

Edit: True, Joe, it does not add it to DAY 0, it adds 0 (days) to the number of days which basically just converts it back to a datetime.

Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY,17);
cal.set(Calendar.MINUTE,30);
cal.set(Calendar.SECOND,0);
cal.set(Calendar.MILLISECOND,0);

Date d = cal.getTime();

• Joda time
• Calendar doc

The following works as expected:

SELECT  Diff = CASE DATEDIFF(HOUR, StartTime, EndTime)
                    WHEN 0 THEN CAST(DATEDIFF(MINUTE, StartTime, EndTime) AS VARCHAR(10))
                    ELSE CAST(60 - DATEPART(MINUTE, StartTime) AS VARCHAR(10)) +
                        REPLICATE(',60', DATEDIFF(HOUR, StartTime, EndTime) - 1) + 
                        + ',' + CAST(DATEPART(MINUTE, EndTime) AS VARCHAR(10))
                END
FROM    (VALUES 
            (CAST('11:15' AS TIME), CAST('13:15' AS TIME)),
            (CAST('10:45' AS TIME), CAST('18:59' AS TIME)),
            (CAST('10:45' AS TIME), CAST('11:59' AS TIME))
        ) t (StartTime, EndTime);

To get 24 columns, you could use 24 case expressions, something like:

SELECT  [0] = CASE WHEN DATEDIFF(HOUR, StartTime, EndTime) = 0
                        THEN DATEDIFF(MINUTE, StartTime, EndTime)
                    ELSE 60 - DATEPART(MINUTE, StartTime)
                END,
        [1] = CASE WHEN DATEDIFF(HOUR, StartTime, EndTime) = 1 
                        THEN DATEPART(MINUTE, EndTime)
                    WHEN DATEDIFF(HOUR, StartTime, EndTime) > 1 THEN 60
                END,
        [2] = CASE WHEN DATEDIFF(HOUR, StartTime, EndTime) = 2
                        THEN DATEPART(MINUTE, EndTime)
                    WHEN DATEDIFF(HOUR, StartTime, EndTime) > 2 THEN 60
                END -- ETC
FROM    (VALUES 
            (CAST('11:15' AS TIME), CAST('13:15' AS TIME)),
            (CAST('10:45' AS TIME), CAST('18:59' AS TIME)),
            (CAST('10:45' AS TIME), CAST('11:59' AS TIME))
        ) t (StartTime, EndTime);

The following also works, and may end up shorter than repeating the same case expression over and over:

WITH Numbers (Number) AS
(   SELECT  ROW_NUMBER() OVER(ORDER BY t1.N) - 1
    FROM    (VALUES (1), (1), (1), (1), (1), (1)) AS t1 (N)
            CROSS JOIN (VALUES (1), (1), (1), (1)) AS t2 (N)
), YourData AS
(   SELECT  StartTime, EndTime
    FROM    (VALUES 
                (CAST('11:15' AS TIME), CAST('13:15' AS TIME)),
                (CAST('09:45' AS TIME), CAST('18:59' AS TIME)),
                (CAST('10:45' AS TIME), CAST('11:59' AS TIME))
            ) AS t (StartTime, EndTime)
), PivotData AS
(   SELECT  t.StartTime,
            t.EndTime,
            n.Number,
            MinuteDiff = CASE WHEN n.Number = 0 AND DATEDIFF(HOUR, StartTime, EndTime) = 0 THEN DATEDIFF(MINUTE, StartTime, EndTime)
                                WHEN n.Number = 0 THEN 60 - DATEPART(MINUTE, StartTime)
                                WHEN DATEDIFF(HOUR, t.StartTime, t.EndTime) <= n.Number THEN DATEPART(MINUTE, EndTime)
                                ELSE 60
                            END
    FROM    YourData AS t
            INNER JOIN Numbers AS n
                ON n.Number <= DATEDIFF(HOUR, StartTime, EndTime)
)
SELECT  *
FROM    PivotData AS d
        PIVOT 
        (   MAX(MinuteDiff)
            FOR Number IN 
            (   [0], [1], [2], [3], [4], [5], 
                [6], [7], [8], [9], [10], [11],
                [12], [13], [14], [15], [16], [17], 
                [18], [19], [20], [21], [22], [23]
            ) 
        ) AS pvt;

It works by joining to a table of 24 numbers, so the case expression doesn't need to be repeated, then rolling these 24 numbers back up into columns using PIVOT

Probably because your java date has a different format from mysql format (YYYY-MM-DD HH:MM:SS)

do this

 DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
 Date date = new Date();
 System.out.println(dateFormat.format(date));

I agree with the previous answers, and is fine if you are ok to start in UTC. But I think it is also a common scenario for people to work with a tz aware value that has a datetime that has a non UTC local timezone.

If you were to just go by name, one would probably infer replace() will be applicable and produce the right datetime aware object. This is not the case.

the replace( tzinfo=... ) seems to be random in its behaviour. It is therefore useless. Do not use this!

localize is the correct function to use. Example:

localdatetime_aware = tz.localize(datetime_nonaware)

Or a more complete example:

import pytz
from datetime import datetime
pytz.timezone('Australia/Melbourne').localize(datetime.now())

gives me a timezone aware datetime value of the current local time:

datetime.datetime(2017, 11, 3, 7, 44, 51, 908574, tzinfo=<DstTzInfo 'Australia/Melbourne' AEDT+11:00:00 DST>)

JavaScript normally convert local timezone to UTC .

date = new Date();
date.setMinutes(date.getMinutes()-date.getTimezoneOffset())
JSON.stringify(date)

This I use because I can understand and hence remember it better (and date time format also can be customized based on your choice) :-

import datetime
moment = datetime.datetime.now()
print("{}/{}/{} {}:{}:{}".format(moment.day, moment.month, moment.year,
                                 moment.hour, moment.minute, moment.second))

from datetime import datetime

date = datetime.today().date()

print(date)

I have a similar situation but I want a consistent way to be able to use DateTime.Parse from the filename as well, so I went with

DateTime.Now.ToString("s").Replace(":", ".") // <-- 2016-10-25T16.50.35

When I want to parse, I can simply reverse the Replace call. This way I don't have to type in any yymmdd stuff or guess what formats DateTime.Parse allows.

As of .NET 4.6, you can use a DateTimeOffset object to get the unix milliseconds. It has a constructor which takes a DateTime object, so you can just pass in your object as demonstrated below.

DateTime yourDateTime;
long yourDateTimeMilliseconds = new DateTimeOffset(yourDateTime).ToUnixTimeMilliseconds();

As noted in other answers, make sure yourDateTime has the correct Kind specified, or use .ToUniversalTime() to convert it to UTC time first.

Here you can learn more about DateTimeOffset.

I've had issues using AddDays(-1).

My solution is TimeSpan.

DateTime.Now - TimeSpan.FromDays(1);

Pyromancer's answer seems pretty good to me, but maybe you wanted:

DateTime.Now.Millisecond

But if you are comparing dates, TimeSpan is the way to go.

The main misunderstanding in MySQL with timestamps is that MySQL by default both returns and stores timestamps without a fractional part.

SELECT current_timestamp()  => 2018-01-18 12:05:34

which can be converted to seconds timestamp as

SELECT UNIX_TIMESTAMP(current_timestamp()) => 1516272429

To add fractional part:

SELECT current_timestamp(3) => 2018-01-18 12:05:58.983

which can be converted to microseconds timestamp as

SELECT CAST( 1000*UNIX_TIMESTAMP(current_timestamp(3)) AS UNSIGNED INTEGER) ts => 1516272274786

There are few tricks with storing in tables. If your table was created like

    CREATE TABLE `ts_test_table` (
      `id` int(1) NOT NULL,
      `not_fractional_timestamp` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

than MySQL will NOT store fractional part within it:

    id, not_fractional_timestamp
    1,  2018-01-18 11:35:12

If you want to add fractional part into your table, you need to create your table in another way:

    CREATE TABLE `ts_test_table2` (
      `id` int(1) NOT NULL,
      `some_data` varchar(10) COLLATE utf8mb4_unicode_ci NOT NULL,
      `fractional_timestamp` timestamp(3) NULL DEFAULT CURRENT_TIMESTAMP(3) ON UPDATE CURRENT_TIMESTAMP(3),
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

that leads to required result:

    id, some_data, fractional_timestamp
    1,  8,         2018-01-18 11:45:40.811

current_timestamp() function is allowed to receive value up to 6, but I've found out (at least in my installed MySQL 5.7.11 version on Windows) that fraction precision 6 leads to the same constant value of 3 digits at the tail, in my case 688

    id, some_data, fractional_timestamp
    1,  2,         2018-01-18 12:01:54.167688
    2,  4,         2018-01-18 12:01:58.893688

That means that really usable timestamp precision of MySQL is platform-dependent:

• on Windows: 3
• on Linux: 6

Other answers using datetime and comparisons also work for time only, without a date.

For example, to check if right now it is more or less than 8:00 a.m., we can use:

import datetime

eight_am = datetime.time( 8,0,0 ) # Time, without a date

And later compare with:

datetime.datetime.now().time() > eight_am  

which will return True

>>> pd.Timestamp('2014-01-23 00:00:00', tz=None).to_datetime()
datetime.datetime(2014, 1, 23, 0, 0)
>>> pd.Timestamp(datetime.date(2014, 3, 26))
Timestamp('2014-03-26 00:00:00')

I'm not allowed to write any comments yet, so I'll write an answer, if somebody will read all of them and reach this one.

If the index of the dataset is a datetime and you want to filter that just by (for example) months, you can do following:

df.loc[df.index.month == 3]

That will filter the dataset for you by March.

select DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE())-1, 0) --First day of previous month
select DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) --Last Day of previous month

If you use MVC, tables, it works like this:

<td>@(((DateTime)detalle.fec).ToString("dd'/'MM'/'yyyy"))</td>

you can use a string formatter to pad any integer with zeros. It acts just like C's printf.

>>> d = datetime.date.today()
>>> '%02d' % d.month
'03'

Updated for py36: Use f-strings! For general ints you can use the d formatter and explicitly tell it to pad with zeros:

 >>> d = datetime.date.today()
 >>> f"{d.month:02d}"
 '07'

But datetimes are special and come with special formatters that are already zero padded:

 >>> f"{d:%d}"  # the day
 '01'
 >>> f"{d:%m}"  # the month
 '07'

A simple function to perform this calculation:

function getMinutesBetweenDates(startDate, endDate) {
    var diff = endDate.getTime() - startDate.getTime();
    return (diff / 60000);
}

This page on MSDN lists standard DateTime format strings, uncluding strings using the 'Z'.

Update: you will need to make sure that the rest of the date string follows the correct pattern as well (you have not supplied an example of what you send it, so it's hard to say whether you did or not). For the UTC format to work it should look like this:

// yyyy'-'MM'-'dd HH':'mm':'ss'Z'
DateTime utcTime = DateTime.Parse("2009-05-07 08:17:25Z");

if (date1.getTime() > date2.getTime()) {
    alert("The first date is after the second date!");
}

Just use:

(DateTime.Now - myDate).TotalHours / 8766.0

The current date - myDate = TimeSpan, get total hours and divide in the total hours per year and get exactly the age/months/days...

$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

Try this;

   public String toDate() {
       DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
       Calendar cal = Calendar.getInstance();
       cal.add(Calendar.DATE, -1);
       return dateFormat.format(cal.getTime());
  }

You could use the excellent Umbrella library:

using nVentive.Umbrella.Extensions.Calendar;
DateTime beginning = DateTime.Now.BeginningOfWeek();

However, they do seem to have stored Monday as the first day of the week (see the property nVentive.Umbrella.Extensions.Calendar.DefaultDateTimeCalendarExtensions.WeekBeginsOn), so that previous localized solution is a bit better. Unfortunate.

Edit: looking closer at the question, it looks like Umbrella might actually work for that too:

// Or DateTime.Now.PreviousDay(DayOfWeek.Monday)
DateTime monday = DateTime.Now.PreviousMonday(); 
DateTime sunday = DateTime.Now.PreviousSunday();

Although it's worth noting that if you ask for the previous Monday on a Monday, it'll give you seven days back. But this is also true if you use BeginningOfWeek, which seems like a bug :(.

SELECT * 
FROM 
     <table_name> 
WHERE 
     <date_field> 
BETWEEN 
     DATE_SUB(NOW(), INTERVAL 1 MONTH) AND NOW();

Similarly, You can select records for 1 month, 2 months etc.

You can, use:

if (date >= startDate && date<= EndDate) { return true; }

The answer is right in the MYSQL manual itself.

"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"

The default date format depends on the language setting for the database server. You can also change it per session, like:

set language french
select cast(getdate() as varchar(50))
-->
févr 8 2013 9:45AM

DateTime.Now returns a DateTime value that consists of the local date and time of the computer where the code is running. It has DateTimeKind.Local assigned to its Kind property. It is equivalent to calling any of the following:

• DateTime.UtcNow.ToLocalTime()
• DateTimeOffset.UtcNow.LocalDateTime
• DateTimeOffset.Now.LocalDateTime
• TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local)
• TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local)

DateTime.Today returns a DateTime value that has the same year, month, and day components as any of the above expressions, but with the time components set to zero. It also has DateTimeKind.Local in its Kind property. It is equivalent to any of the following:

• DateTime.Now.Date
• DateTime.UtcNow.ToLocalTime().Date
• DateTimeOffset.UtcNow.LocalDateTime.Date
• DateTimeOffset.Now.LocalDateTime.Date
• TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local).Date
• TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local).Date

Note that internally, the system clock is in terms of UTC, so when you call DateTime.Now it first gets the UTC time (via the GetSystemTimeAsFileTime function in the Win32 API) and then it converts the value to the local time zone. (Therefore DateTime.Now.ToUniversalTime() is more expensive than DateTime.UtcNow.)

Also note that DateTimeOffset.Now.DateTime will have similar values to DateTime.Now, but it will have DateTimeKind.Unspecified rather than DateTimeKind.Local - which could lead to other errors depending on what you do with it.

So, the simple answer is that DateTime.Today is equivalent to DateTime.Now.Date.
But IMHO - You shouldn't use either one of these, or any of the above equivalents.

When you ask for DateTime.Now, you are asking for the value of the local calendar clock of the computer that the code is running on. But what you get back does not have any information about that clock! The best that you get is that DateTime.Now.Kind == DateTimeKind.Local. But whose local is it? That information gets lost as soon as you do anything with the value, such as store it in a database, display it on screen, or transmit it using a web service.

If your local time zone follows any daylight savings rules, you do not get that information back from DateTime.Now. In ambiguous times, such as during a "fall-back" transition, you won't know which of the two possible moments correspond to the value you retrieved with DateTime.Now. For example, say your system time zone is set to Mountain Time (US & Canada) and you ask for DateTime.Now in the early hours of November 3rd, 2013. What does the result 2013-11-03 01:00:00 mean? There are two moments of instantaneous time represented by this same calendar datetime. If I were to send this value to someone else, they would have no idea which one I meant. Especially if they are in a time zone where the rules are different.

The best thing you could do would be to use DateTimeOffset instead:

// This will always be unambiguous.
DateTimeOffset now = DateTimeOffset.Now;

Now for the same scenario I described above, I get the value 2013-11-03 01:00:00 -0600 before the transition, or 2013-11-03 01:00:00 -0700 after the transition. Anyone looking at these values can tell what I meant.

I wrote a blog post on this very subject. Please read - The Case Against DateTime.Now.

Also, there are some places in this world (such as Brazil) where the "spring-forward" transition happens exactly at Midnight. The clocks go from 23:59 to 01:00. This means that the value you get for DateTime.Today on that date, does not exist! Even if you use DateTimeOffset.Now.Date, you are getting the same result, and you still have this problem. It is because traditionally, there has been no such thing as a Date object in .Net. So regardless of how you obtain the value, once you strip off the time - you have to remember that it doesn't really represent "midnight", even though that's the value you're working with.

If you really want a fully correct solution to this problem, the best approach is to use NodaTime. The LocalDate class properly represents a date without a time. You can get the current date for any time zone, including the local system time zone:

using NodaTime;
...

Instant now = SystemClock.Instance.Now;

DateTimeZone zone1 = DateTimeZoneProviders.Tzdb.GetSystemDefault();
LocalDate todayInTheSystemZone = now.InZone(zone1).Date;

DateTimeZone zone2 = DateTimeZoneProviders.Tzdb["America/New_York"];
LocalDate todayInTheOtherZone = now.InZone(zone2).Date;

If you don't want to use Noda Time, there is now another option. I've contributed an implementation of a date-only object to the .Net CoreFX Lab project. You can find the System.Time package object in their MyGet feed. Once added to your project, you will find you can do any of the following:

using System;
...

Date localDate = Date.Today;

Date utcDate = Date.UtcToday;

Date tzSpecificDate = Date.TodayInTimeZone(anyTimeZoneInfoObject);

There's more then one way to do this with DateTime which was introduced in PHP 5.2. Unlike using strtotime() this will account for daylight savings time and leap year.

$datetime = new DateTime('2013-01-29');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

// Available in PHP 5.3

$datetime = new DateTime('2013-01-29');
$datetime->add(new DateInterval('P1D'));
echo $datetime->format('Y-m-d H:i:s');

// Available in PHP 5.4

echo (new DateTime('2013-01-29'))->add(new DateInterval('P1D'))->format('Y-m-d H:i:s');

// Available in PHP 5.5

$start = new DateTimeImmutable('2013-01-29');
$datetime = $start->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

For case when your interval's end it's date without hours like "from 2017-01-01 to whole day of 2017-01-16" it's better to adjust interval's to 23 hours 59 minutes and 59 seconds like:

end = end.Add(time.Duration(23*time.Hour) + time.Duration(59*time.Minute) + time.Duration(59*time.Second)) 

if now.After(start) && now.Before(end) {
    ...
}

I solved this problem like this:

import calendar
from datetime import datetime
moths2add = 6
now = datetime.now()
current_year = now.year
current_month = now.month
#count days in months you want to add using calendar module
days = sum(
  [calendar.monthrange(current_year, elem)[1] for elem in range(current_month, current_month + moths)]
    )
print now + days

Dominc has the right idea, but put the calculation on the other side of the expression.

SELECT * FROM my_table WHERE endTime < DATE_SUB(CONVERT_TZ(NOW(), @@global.time_zone, 'GMT'), INTERVAL 30 MINUTE)

This has the advantage that you're doing the 30 minute calculation once instead of on every row. That also means MySQL can use the index on that column. Both of thse give you a speedup.

Since strptime returns a datetime object which has tzinfo attribute, We can simply replace it with desired timezone.

>>> import datetime

>>> date_time_str = '2018-06-29 08:15:27.243860'
>>> date_time_obj = datetime.datetime.strptime(date_time_str, '%Y-%m-%d %H:%M:%S.%f').replace(tzinfo=datetime.timezone.utc)
>>> date_time_obj.tzname()
'UTC'

Following Joe's example value above, I'd use the modulus arithmetic operator, thusly:

td = datetime.timedelta(hours=10.56)
td_str = "%d:%d" % (td.seconds/3600, td.seconds%3600/60)

Note that integer division in Python rounds down by default; if you want to be more explicit, use math.floor() or math.ceil() as appropriate.

select from_unixtime(column,'%Y-%m-%d') from myTable; 

If you are using two DateTime objects, one to store the date the other the time, you could do the following:

var date = new DateTime(2016,6,28);

var time = new DateTime(1,1,1,13,13,13);

var combinedDateTime = date.AddTicks(time.TimeOfDay.Ticks);

An example of this can be found here

Here is a simple solution:

import pandas as pd
# convert the timestamp column to datetime
df['timestamp'] = pd.to_datetime(df['timestamp'])

# extract hour from the timestamp column to create an time_hour column
df['time_hour'] = df['timestamp'].dt.hour

I'd consider using a nullable types.

DateTime? myDate instead of DateTime myDate.

All the Answers are Quite great but if you want to use a single function ,this may work.

private bool validateTime(string dateInString)
{
    DateTime temp;
    if (DateTime.TryParse(dateInString, out temp))
    {
       return true;
    }
    return false;
}

It should be just DateTime.ToString( "MMMM" )

You don't need all the extra Ms.

This will give you the time you want (eg: 21:31 PM)

//Add 2 Hours to just TIME
SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss a");
Date date2 = formatter.parse("19:31:51 PM");
Calendar cal2 = Calendar.getInstance();
cal2.setTime(date2);
cal2.add(Calendar.HOUR_OF_DAY, 2);
SimpleDateFormat printTimeFormat = new SimpleDateFormat("HH:mm a");
System.out.println(printTimeFormat.format(cal2.getTime())); 

In general case you need to compare DateTimes with the same Kind:

if (date1.ToUniversalTime() < date2.ToUniversalTime())
    Console.WriteLine("date1 is earlier than date2");

Explanation from MSDN about DateTime.Compare (This is also relevant for operators like >, <, == and etc.):

To determine the relationship of t1 to t2, the Compare method compares the Ticks property of t1 and t2 but ignores their Kind property. Before comparing DateTime objects, ensure that the objects represent times in the same time zone.

Thus, a simple comparison may give an unexpected result when dealing with DateTimes that are represented in different timezones.

If you would like to work with a textbox, be aware that setting the TextMode property to "Date" will not work on Internet Explorer 11, because it does not currently support the "Date", "DateTime", nor "Time" values.

This example illustrates how to implement it using a textbox, including validation of the dates (since the user could enter just numbers). It will work on Internet Explorer 11 as well other web browsers.

<asp:Content ID="Content"
         ContentPlaceHolderID="MainContent"
         runat="server">

<link rel="stylesheet"
    href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" />
   <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
   <script>
   $(function () {
   $("#
   <%= txtBoxDate.ClientID %>").datepicker();
   });
 </script>
 <asp:TextBox ID="txtBoxDate"
           runat="server"
           Width="135px"
           AutoPostBack="False"
           TabIndex="1"
           placeholder="mm/dd/yyyy"
           autocomplete="off"
           MaxLength="10"></asp:TextBox>
 <asp:CompareValidator ID="CompareValidator1"
                    runat="server"
                    ControlToValidate="txtBoxDate"
                    Operator="DataTypeCheck"
                    Type="Date">Date invalid, please check format. 
 </asp:CompareValidator>
 </asp:Content>

This one worked for me:

>> print(df)
                          TotalVolume  Symbol
2016-04-15 09:00:00       108400       2802.T
2016-04-15 09:05:00       50300        2802.T

>> print(df.set_index(pd.to_datetime(df.index.values) - datetime(2016, 4, 15)))

             TotalVolume  Symbol
09:00:00     108400       2802.T
09:05:00     50300        2802.T

try this:

var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours()+':'+today.getMinutes()+':'+today.getSeconds();
console.log(date + ' '+ time);

I tried using the dtypes=[datetime, ...] option, but

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

I encountered the following error:

TypeError: data type not understood

The only change I had to make is to replace datetime with datetime.datetime

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime.datetime, datetime.datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

Note: This answer shows how to achieve this using only the datetime and calendar standard library (stdlib) modules - which is what was explicitly asked for. The accepted answer shows how to better achieve this with one of the many dedicated non-stdlib libraries. If you can use non-stdlib libraries, by all means do so for these kinds of date/time manipulations!

How about this?

def add_one_month(orig_date):
    # advance year and month by one month
    new_year = orig_date.year
    new_month = orig_date.month + 1
    # note: in datetime.date, months go from 1 to 12
    if new_month > 12:
        new_year += 1
        new_month -= 12

    new_day = orig_date.day
    # while day is out of range for month, reduce by one
    while True:
        try:
            new_date = datetime.date(new_year, new_month, new_day)
        except ValueError as e:
            new_day -= 1
        else:
            break

    return new_date

EDIT:

Improved version which:

1. keeps the time information if given a datetime.datetime object
2. doesn't use try/catch, instead using calendar.monthrange from the calendar module in the stdlib:

import datetime
import calendar

def add_one_month(orig_date):
    # advance year and month by one month
    new_year = orig_date.year
    new_month = orig_date.month + 1
    # note: in datetime.date, months go from 1 to 12
    if new_month > 12:
        new_year += 1
        new_month -= 12

    last_day_of_month = calendar.monthrange(new_year, new_month)[1]
    new_day = min(orig_date.day, last_day_of_month)

    return orig_date.replace(year=new_year, month=new_month, day=new_day)

If the date is valid then the getTime() will always be equal to itself.

var date = new Date('2019-12-12');
if(date.getTime() - date.getTime() === 0) {
    console.log('Date is valid');
} else {
    console.log('Date is invalid');
}

1. The class Date/Timestamp represents a specific instant in time, with millisecond precision, since January 1, 1970, 00:00:00 GMT. So this time difference (from epoch to current time) will be same in all computers across the world with irrespective of Timezone.

2. Date/Timestamp doesn't know about the given time is on which timezone.

3. If we want the time based on timezone we should go for the Calendar or SimpleDateFormat classes in java.

4. If you try to print a Date/Timestamp object using toString(), it will convert and print the time with the default timezone of your machine.

5. So we can say (Date/Timestamp).getTime() object will always have UTC (time in milliseconds)

6. To conclude Date.getTime() will give UTC time, but toString() is on locale specific timezone, not UTC.

Now how will I create/change time on specified timezone?

The below code gives you a date (time in milliseconds) with specified timezones. The only problem here is you have to give date in string format.

   DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HH:mm:ss");
   dateFormatLocal.setTimeZone(timeZone);
   java.util.Date parsedDate = dateFormatLocal.parse(date);

Use dateFormat.format for taking input Date (which is always UTC), timezone and return date as String.

How to store UTC/GMT time in DB:

If you print the parsedDate object, the time will be in default timezone. But you can store the UTC time in DB like below.

        Calendar calGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        Timestamp tsSchedStartTime = new Timestamp (parsedDate.getTime());
        if (tsSchedStartTime != null) {
            stmt.setTimestamp(11, tsSchedStartTime, calGMT );
        } else {
            stmt.setNull(11, java.sql.Types.DATE);
        }

This code block uses universal time to convert current DateTime object then converts it back to local DateTime. Works perfect for me I hope it helps!

CreatedDate.ToUniversalTime().ToLocalTime();

Try this code....

$chu = curl_init();

curl_setopt($chu, CURLOPT_URL, 'http://www.myapp.com/test.php?someprm=xyz');

curl_setopt($chu, CURLOPT_FRESH_CONNECT, true);
curl_setopt($chu, CURLOPT_TIMEOUT, 1);

curl_exec($chu);
curl_close($chu);

Please dont forget to enable CURL php extension.

if you want to shrink one slide for instance, add shapes to hide the unwanted background margins. you can set the shape color filling as the background (gray or black). It's "ugly" but it works

int segundo = 0;
DateTime dt = new DateTime();

private void timer1_Tick(object sender, EventArgs e){
    segundo++;
    label1.Text = dt.AddSeconds(segundo).ToString("HH:mm:ss");
}

You can use the .indexOf() and .substring(), like this:

var url = "www.aaa.com/task1/1.3.html#a_1";
var hash = url.substring(url.indexOf("#")+1);

You can give it a try here, if it may not have a # in it, do an if(url.indexOf("#") != -1) check like this:

var url = "www.aaa.com/task1/1.3.html#a_1", idx = url.indexOf("#");
var hash = idx != -1 ? url.substring(idx+1) : "";

If this is the current page URL, you can just use window.location.hash to get it, and replace the # if you wish.

Note: This solution only works for Webkit browsers, which incorrectly apply pseudo-elements to self-closing tags.

As an addendum to above answers it is worth noting that in some cases one needs to insert a space instead of merely ignoring <br>:

For instance the above answers will turn

Monday<br>05 August

to

Monday05 August

as I had verified while I tried to format my weekly event calendar. A space after "Monday" is preferred to be inserted. This can be done easily by inserting the following in the CSS:

br  {
    content: ' '
}
br:after {
    content: ' '
}

This will make

Monday<br>05 August

look like

Monday 05 August

You can change the content attribute in br:after to ', ' if you want to separate by commas, or put anything you want within ' ' to make it the delimiter! By the way

Monday, 05 August

looks neat ;-)

See here for a reference.

As in the above answers, if you want to make it tag-specific, you can. As in if you want this property to work for tag <h3>, just add a h3 each before br and br:after, for instance.

It works most generally for a pseudo-tag.

make sure you add {} around Html.RenderPartial, as:

@{Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});}

not

@Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});

But its still giving an error message in Query Builder. I am using SqlServerCe 2008.

SELECT         Products_Master.ProductName, Order_Products.Quantity, Order_Details.TotalTax, Order_Products.Cost, Order_Details.Discount,

I replaced WHERE with HAVING as said by @powerlord. But still showing an error.

Hashicorp's https://github.com/mitchellh/mapstructure library does this out of the box:

import "github.com/mitchellh/mapstructure"

mapstructure.Decode(myData, &result)

The second result parameter has to be an address of the struct.

This does not work for existing jobs, however there is Jenkins job builder.

This allows one to keep job definitions in yaml files and in a git repo which is very portable.

a simple hack is to rename your package : eg MainActivity to ApplicationMainActivity

Michael-O gave useful approach to solve the problem. Another way to solve this is by starting the server with Putty Console.

Even though its not directly related. But I found that the CALC code won't work if you do not put spaces properly.

So this did not work for me calc(#{$a}+7px)

But this worked calc(#{$a} + 7px)

Took me sometime to figure this out.

Left Semi join : A semi join returns values from the left side of the relation that has a match with the right. It is also referred to as a left semi join.

Note : There is another thing called left anti join : An anti join returns values from the left relation that has no match with the right. It is also referred to as a left anti join.

Inner join : It selects rows that have matching values in both relations.

What can we build with NodeJS:

• Utilities and Tools
• Anything that is not CPU intensive.

There are two other solutions which involve assigning to an index one past the end of the list. Here is a solution that does use append.

resultsa <- list(1,2,3,4,5)
resultsb <- list(6,7,8,9,10)
resultsc <- list(11,12,13,14,15)

outlist <- list(resultsa)
outlist <- append(outlist, list(resultsb))
outlist <- append(outlist, list(resultsc))

which gives your requested format

> str(outlist)
List of 3
 $ :List of 5
  ..$ : num 1
  ..$ : num 2
  ..$ : num 3
  ..$ : num 4
  ..$ : num 5
 $ :List of 5
  ..$ : num 6
  ..$ : num 7
  ..$ : num 8
  ..$ : num 9
  ..$ : num 10
 $ :List of 5
  ..$ : num 11
  ..$ : num 12
  ..$ : num 13
  ..$ : num 14
  ..$ : num 15

I tried a few of these things until I got one to work in both Firefox and IE. This is what I came up with.

$("#my-Select").val($("#my-Select" + " option").filter(function() { return this.text == myText }).val());

another way of writing it in a more readable fasion:

var valofText = $("#my-Select" + " option").filter(function() {
    return this.text == myText
}).val();
$(ElementID).val(valofText);

Pseudocode:

$("#my-Select").val( getValOfText( myText ) );

NaN is a special value that can't be tested like that. An interesting thing I just wanted to share is this

var nanValue = NaN;
if(nanValue !== nanValue) // Returns true!
    alert('nanValue is NaN');

This returns true only for NaN values and Is a safe way of testing. Should definitely be wrapped in a function or atleast commented, because It doesnt make much sense obviously to test if the same variable is not equal to each other, hehe.

Assuming that you have a program running in the foreground, press ctrl-Z, then:

[1]+  Stopped                 myprogram
$ disown -h %1
$ bg 1
[1]+ myprogram &
$ logout

If there is only one job, then you don't need to specify the job number. Just use disown -h and bg.

Explanation of the above steps:

You press ctrl-Z. The system suspends the running program, displays a job number and a "Stopped" message and returns you to a bash prompt.

You type the disown -h %1 command (here, I've used a 1, but you'd use the job number that was displayed in the Stopped message) which marks the job so it ignores the SIGHUP signal (it will not be stopped by logging out).

Next, type the bg command using the same job number; this resumes the running of the program in the background and a message is displayed confirming that.

You can now log out and it will continue running..

This problem is just because you have declared the column in CHAR, VARCHAR or TEXT datatype. Just change the datatype to INT, BIGINT etc. This is will solved the problem of your custom ordering.

It seems that the deletion command was not officially documented in Kafka 0.8.1.x because of a known bug (https://issues.apache.org/jira/browse/KAFKA-1397).

Nevertheless, the command was still shipped in the code and can be executed as:

bin/kafka-run-class.sh kafka.admin.DeleteTopicCommand --zookeeper localhost:2181 --topic test

In the meantime, the bug got fixed and the deletion command is now officially available from Kafka 0.8.2.0 as:

bin/kafka-topics.sh --delete --zookeeper localhost:2181 --topic test

You just add the following line to your local ~/.gemrc file (it is in your home folder):

gem: --no-document

or you can add this line to the global gemrc config file.

Here is how to find it (in Linux):

strace gem source 2>&1 | grep gemrc

No one mentioned the short form of the .format method:

Needs at least Python 3.6

f"{Decimal('40800000000.00000000000000'):.2E}"

(I believe it's the same as Cees Timmerman, just a bit shorter)

Here is your answer. We can use both simultaniously. As i used both and they are working fine. The code is as follows:

<EditText
    android:id="@+id/edittext_password_la"
    android:layout_below="@+id/edittext_username_la"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="15dip"
    android:inputType="textPassword"
    android:hint="@string/string_password" />

This will help you.

1. Remove all docker processes:

   docker rm $(docker ps -a -q)
   

2. Remove specific container:

   $ docker ps -a (lists all old containers)
   
   $ docker rm container-Id
   

Briefly:

1. Get the self signed certificate
2. Put it into some (e.g. ~/git-certs/cert.pem) file
3. Set git to trust this certificate using http.sslCAInfo parameter

In more details:

Get self signed certificate of remote server

Assuming, the server URL is repos.sample.com and you want to access it over port 443.

There are multiple options, how to get it.

Get certificate using openssl

$ openssl s_client -connect repos.sample.com:443

Catch the output into a file cert.pem and delete all but part between (and including) -BEGIN CERTIFICATE- and -END CERTIFICATE-

Content of resulting file ~/git-certs/cert.pem may look like this:

-----BEGIN CERTIFICATE-----

Get certificate using your web browser

I use Redmine with Git repositories and I access the same URL for web UI and for git command line access. This way, I had to add exception for that domain into my web browser.

Using Firefox, I went to Options -> Advanced -> Certificates -> View Certificates -> Servers, found there the selfsigned host, selected it and using Export button I got exactly the same file, as created using openssl.

Note: I was a bit surprised, there is no name of the authority visibly mentioned. This is fine.

Having the trusted certificate in dedicated file

Previous steps shall result in having the certificate in some file. It does not matter, what file it is as long as it is visible to your git when accessing that domain. I used ~/git-certs/cert.pem

Note: If you need more trusted selfsigned certificates, put them into the same file:

-----BEGIN CERTIFICATE-----
MIIDnzCCAocCBE/xnXAwDQYJKoZIhvcNAQEFBQAwgZMxCzAJBgNVBAYTAkRFMRUw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
AnOtHeRtRuStEdCeRtIfIcAtEgOeShErExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----

This shall work (but I tested it only with single certificate).

Configure git to trust this certificate

$ git config --global http.sslCAInfo /home/javl/git-certs/cert.pem

You may also try to do that system wide, using --system instead of --global.

And test it: You shall now be able communicating with your server without resorting to:

$ git config --global http.sslVerify false #NO NEED TO USE THIS

If you already set your git to ignorance of ssl certificates, unset it:

$ git config --global --unset http.sslVerify

and you may also check, that you did it all correctly, without spelling errors:

$ git config --global --list

what should list all variables, you have set globally. (I mispelled http to htt).

Here is another way without regex.

$myUrl = "http://www.domain.com/link.php";
$myParsedURL = parse_url($myUrl);
$myDomainName= $myParsedURL['host'];
$ipAddress = gethostbyname($myDomainName);
if($ipAddress == $myDomainName)
{
   echo "There is no url";
}
else
{
   echo "url found";
}

The reason why @Resource(name = "{your child class name}") works but @Autowired sometimes don't work is because of the difference of their Matching sequence

Matching sequence of @Autowire
Type, Qualifier, Name

Matching sequence of @Resource
Name, Type, Qualifier

The more detail explanation can be found here:
Inject and Resource and Autowired annotations

In this case, different child class inherited from the parent class or interface confuses @Autowire, because they are from same type; As @Resource use Name as first matching priority , it works.

Qiqi Abaziz's answer is ok, but I still struggled for a long time getting it to work with the compatibility pack and to apply the style to the correct elements. Also, the transparency-hack is unneccessary. So here is a complete example working for v8 and up:

values\styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="MyActivityTheme" parent="@style/Theme.AppCompat">
        <item name="actionBarStyle">@style/NoLogoActionBar</item> <!-- pre-v11-compatibility -->
        <item name="android:actionBarStyle">@style/NoLogoActionBar</item>
    </style>
    <style name="NoLogoActionBar" parent="@style/Widget.AppCompat.ActionBar">
        <item name="displayOptions">showHome</item> <!-- pre-v11-compatibility -->
        <item name="android:displayOptions">showHome</item>
    </style>
</resources>

AndroidManifest.xml (shell)

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">   
    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="19"/>
    <application android:theme="@android:style/Theme.Light.NoTitleBar">
        <activity android:theme="@style/PentActivityTheme"/>
    </application>
</manifest>

I've been battling this kind of problem for a while, and I think I've come up with a reliable solution.

It's pretty difficult to know for sure that this.getActivity() isn't going to return null for a Fragment, especially if you're dealing with any kind of network behaviour which gives your code ample time to withdraw Activity references.

In the solution below, I declare a small management class called the ActivityBuffer. Essentially, this class deals with maintaining a reliable reference to an owning Activity, and promising to execute Runnables within a valid Activity context whenever there's a valid reference available. The Runnables are scheduled for execution on the UI Thread immediately if the Context is available, otherwise execution is deferred until that Context is ready.

/** A class which maintains a list of transactions to occur when Context becomes available. */
public final class ActivityBuffer {

    /** A class which defines operations to execute once there's an available Context. */
    public interface IRunnable {
        /** Executes when there's an available Context. Ideally, will it operate immediately. */
        void run(final Activity pActivity);
    }

    /* Member Variables. */
    private       Activity        mActivity;
    private final List<IRunnable> mRunnables;

    /** Constructor. */
    public ActivityBuffer() {
        // Initialize Member Variables.
        this.mActivity  = null;
        this.mRunnables = new ArrayList<IRunnable>();
    }

    /** Executes the Runnable if there's an available Context. Otherwise, defers execution until it becomes available. */
    public final void safely(final IRunnable pRunnable) {
        // Synchronize along the current instance.
        synchronized(this) {
            // Do we have a context available?
            if(this.isContextAvailable()) {
                // Fetch the Activity.
                final Activity lActivity = this.getActivity();
                // Execute the Runnable along the Activity.
                lActivity.runOnUiThread(new Runnable() { @Override public final void run() { pRunnable.run(lActivity); } });
            }
            else {
                // Buffer the Runnable so that it's ready to receive a valid reference.
                this.getRunnables().add(pRunnable);
            }
        }
    }

    /** Called to inform the ActivityBuffer that there's an available Activity reference. */
    public final void onContextGained(final Activity pActivity) {
        // Synchronize along ourself.
        synchronized(this) {
            // Update the Activity reference.
            this.setActivity(pActivity);
            // Are there any Runnables awaiting execution?
            if(!this.getRunnables().isEmpty()) {
                // Iterate the Runnables.
                for(final IRunnable lRunnable : this.getRunnables()) {
                    // Execute the Runnable on the UI Thread.
                    pActivity.runOnUiThread(new Runnable() { @Override public final void run() {
                        // Execute the Runnable.
                        lRunnable.run(pActivity);
                    } });
                }
                // Empty the Runnables.
                this.getRunnables().clear();
            }
        }
    }

    /** Called to inform the ActivityBuffer that the Context has been lost. */
    public final void onContextLost() {
        // Synchronize along ourself.
        synchronized(this) {
            // Remove the Context reference.
            this.setActivity(null);
        }
    }

    /** Defines whether there's a safe Context available for the ActivityBuffer. */
    public final boolean isContextAvailable() {
        // Synchronize upon ourself.
        synchronized(this) {
            // Return the state of the Activity reference.
            return (this.getActivity() != null);
        }
    }

    /* Getters and Setters. */
    private final void setActivity(final Activity pActivity) {
        this.mActivity = pActivity;
    }

    private final Activity getActivity() {
        return this.mActivity;
    }

    private final List<IRunnable> getRunnables() {
        return this.mRunnables;
    }

}

In terms of its implementation, we must take care to apply the life cycle methods to coincide with the behaviour described above by Pawan M:

public class BaseFragment extends Fragment {

    /* Member Variables. */
    private ActivityBuffer mActivityBuffer;

    public BaseFragment() {
        // Implement the Parent.
        super();
        // Allocate the ActivityBuffer.
        this.mActivityBuffer = new ActivityBuffer();
    }

    @Override
    public final void onAttach(final Context pContext) {
        // Handle as usual.
        super.onAttach(pContext);
        // Is the Context an Activity?
        if(pContext instanceof Activity) {
            // Cast Accordingly.
            final Activity lActivity = (Activity)pContext;
            // Inform the ActivityBuffer.
            this.getActivityBuffer().onContextGained(lActivity);
        }
    }

    @Deprecated @Override
    public final void onAttach(final Activity pActivity) {
        // Handle as usual.
        super.onAttach(pActivity);
        // Inform the ActivityBuffer.
        this.getActivityBuffer().onContextGained(pActivity);
    }

    @Override
    public final void onDetach() {
        // Handle as usual.
        super.onDetach();
        // Inform the ActivityBuffer.
        this.getActivityBuffer().onContextLost();
    }

    /* Getters. */
    public final ActivityBuffer getActivityBuffer() {
        return this.mActivityBuffer;
    }

}

Finally, in any areas within your Fragment that extends BaseFragment that you're untrustworthy about a call to getActivity(), simply make a call to this.getActivityBuffer().safely(...) and declare an ActivityBuffer.IRunnable for the task!

The contents of your void run(final Activity pActivity) are then guaranteed to execute along the UI Thread.

The ActivityBuffer can then be used as follows:

this.getActivityBuffer().safely(
  new ActivityBuffer.IRunnable() {
    @Override public final void run(final Activity pActivity) {
       // Do something with guaranteed Context.
    }
  }
);

If you want to send an arbitrary amount of data to your server, POST is the only reliable method to do that. GET would also be possible but clients and servers allow just a limited URL length (something like 2048 characters).

For this particular case looks like using a directive to dynamically create the component would be a better option. Example:

In the HTML where you want to create the component

<ng-container dynamicComponentDirective [someConfig]="someConfig"></ng-container>

I would approach and design the directive in the following way.

const components: {[type: string]: Type<YourConfig>} = {
    text : TextEditorComponent,
    numeric: NumericComponent,
    string: StringEditorComponent,
    date: DateComponent,
    ........
    .........
};

@Directive({
    selector: '[dynamicComponentDirective]'
})
export class DynamicComponentDirective implements YourConfig, OnChanges, OnInit {
    @Input() yourConfig: Define your config here //;
    component: ComponentRef<YourConfig>;

    constructor(
        private resolver: ComponentFactoryResolver,
        private container: ViewContainerRef
    ) {}

    ngOnChanges() {
        if (this.component) {
            this.component.instance.config = this.config;
            // config is your config, what evermeta data you want to pass to the component created.
        }
    }

    ngOnInit() {
        if (!components[this.config.type]) {
            const supportedTypes = Object.keys(components).join(', ');
            console.error(`Trying to use an unsupported type ${this.config.type} Supported types: ${supportedTypes}`);
        }

        const component = this.resolver.resolveComponentFactory<yourConfig>(components[this.config.type]);
        this.component = this.container.createComponent(component);
        this.component.instance.config = this.config;
    }
}

So in your components text, string, date, whatever - whatever the config you have been passing in the HTML in the ng-container element would be available.

The config, yourConfig, can be the same and define your metadata.

Depending on your config or input type the directive should act accordingly and from the supported types, it would render the appropriate component. If not it will log an error.

Sometime only this helps:

View child = parent.findViewById(R.id.btnMoreText);
    child.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            View parent = (View) v.getParent();
            parent.performClick();
        }
    });

Another variant, works not always:

child.setOnClickListener(null);

The query method can return false instead of a result set in case there is an error. That is why you get the error on the fetch_assoc method call, which obviously does not exist when $result is false.

This means you have an error in your SELECT statement. To get that error displayed, do this:

 $result = $conn->query($sql) or die($conn->error);

Most probably you have a wrong spelling for the table name or a column name. Maybe when moving to the host you did not create that table correctly, and made a spelling mistake there.

You should in fact see the same error when executing the same query via phpAdmin.

Also, replace this line:

while(($row = $result->fetch_assoc()) !== null){

with just:

while($row = $result->fetch_assoc()) {

You could also add this for debugging:

echo "number of rows: " . $result->num_rows;

Your code is correct you just used .div instead of div

HTML

<div class="ui grid container">
<div class="ui center aligned three column grid">
  <div class="column">
  </div>
  <div class="column">
    </div>
  </div>

CSS

div{
position: absolute;
top: 50%;
left: 50%;
margin-top: -50px;
margin-left: -50px;
width: 100px;
height: 100px;
}

Check out this Fiddle

table_ages <- subset(infert, select=c("age"))
summary(table_ages)
#            age       
#  Min.   :21.00  
#  1st Qu.:28.00  
#  Median :31.00  
#  Mean   :31.50  
#  3rd Qu.:35.25  
#  Max.   :44.00  

This is probably what they're looking for. summary(...) applied to a numeric returns the min, max, mean, median, and 25th and 75th percentile of the data.

Note that

summary(infert$age)
#    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
#   21.00   28.00   31.00   31.50   35.25   44.00 

The numbers are the same but the format is different. This is because table_ages is a data frame with one column (ages), whereas infert$age is a numeric vector. Try typing summary(infert).

onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"

Change 1000 to the number of milliseconds you want to delay.

regex: /^[a-zA-Z0-9_.]$/i

This works

I like to stay away from the marshaller.

Using CString newString(originalString);

Seems much cleaner and faster to me. No need to worry about creating and deleting a context.

First install the required library globally on your computer:

npm install -g ios-deploy

Go to your settings on your iPhone to find the name of the device.

Then provide that below like:

react-native run-ios --device "______\'s iPhone"

Sometimes this will fail and output a message like this:

Found Xcode project ________.xcodeproj
Could not find device with the name: "_______'s iPhone".
Choose one of the following:
______’s iPhone Udid: _________

That udid is used like this:

react-native run-ios --udid 0412e2c230a14e23451699

Optionally you may use:

react-native run-ios --udid 0412e2c230a14e23451699 -- configuration Release

The best source I have for this kind of question is this page: http://www.quirksmode.org/js/keys.html

What they say is that the key codes are odd on Safari, and consistent everywhere else (except that there's no keypress event on IE, but I believe keydown works).

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

If you want to only pass certain arguments, you can do so like this:

Foo.bar(TheClass, 'theMethod', 'arg1', 'arg2')

Foo.js

bar (obj, method, ...args) {
  obj[method](...args)
}

obj and method are used by the bar() method, while the rest of args are passed to the actual call.

The classes which you are importing have to be on the classpath. So either the users of your Applet have to have the libraries in the right place or you simply provide those libraries by including them in your jar file. For example like this: Easiest way to merge a release into one JAR file

This is the best solution you'll found

var list3 = list1.Where(l => list2.ToList().Contains(l));

A char variable is actually an 8-bit integral value. It will have values from 0 to 255. These are ASCII codes. 0 stands for the C-null character, and 255 stands for an empty symbol.

So, when you write the following assignment:

char a = 'a'; 

It is the same thing as:

char a = 97;

So, you can compare two char variables using the >, <, ==, <=, >= operators:

char a = 'a';
char b = 'b';

if( a < b ) printf("%c is smaller than %c", a, b);
if( a > b ) printf("%c is smaller than %c", a, b);
if( a == b ) printf("%c is equal to %c", a, b);

Try to place the code of your query before. That fix my problem. e.g. change this:

query1 
query2 - get the error 
update

to this:

query2
query1
update

foreach (DataRow row in dt.Rows)
{
    foreach (DataColumn column in dt.Columns)
    {
        ColumnName = column.ColumnName;
        ColumnData = row[column].ToString();
    }
}

use the limit clausule, with the offset to choose the row number -1 so if u wanna get the number 8 row so use:

limit 1 offset 7

For my Android Studio workout. I found that this happen when I change Compile SDK Version from API23 (Android 6) to be API17 (Android 4.2) manually in Project Structure setting, and trying to change some code in layout files.

I miss-understood that I have to change it manually, even on New Project I have selected the "Minimum SdK" to be 4.2 already.

Solve by just change it back to API23, and it still can run on Android 4.2. ^^

Couldn't get anyone of these working so will add my one just in-case it helps.

public class MyEditTextDatePicker  implements OnClickListener, OnDateSetListener {   
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;

public MyEditTextDatePicker(Context context, int editTextViewID)
{       
    Activity act = (Activity)context;
    this._editText = (EditText)act.findViewById(editTextViewID);
    this._editText.setOnClickListener(this);
    this._context = context;
}

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    _birthYear = year;
    _month = monthOfYear;
    _day = dayOfMonth;
    updateDisplay();
}
@Override
public void onClick(View v) {
    Calendar calendar = Calendar.getInstance(TimeZone.getDefault());

    DatePickerDialog dialog = new DatePickerDialog(_context, this,
            calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
            calendar.get(Calendar.DAY_OF_MONTH));
    dialog.show();

}

// updates the date in the birth date EditText
private void updateDisplay() {

    _editText.setText(new StringBuilder()
    // Month is 0 based so add 1
    .append(_day).append("/").append(_month + 1).append("/").append(_birthYear).append(" "));
}
}

Also something that isn't mentioned in the others. Make sure you put the following on EditText xml.

android:focusable="false"

Otherwise like in my case the Keyboard will keep popping up. Hope this helps someone

The above answers give a good insight on how to delete the "Cars"

However, I want this answer to challenge the approach itself:

1- SQLite CoreData is a relational database. In this case, where there isn't any releation, I would advise against using CoreData and maybe using the file system instead, or keep things in memory.

2- In other examples, where "Car" entity have other relations, and therefore CoreData, I would advise against having 2000 cars as root entity. Instead I would give them a parent, let's say "CarsRepository" entity. Then you can give a one-to-many relationship to the "Car" entity, and just replace the relationship to point to the new cars when they are downloaded. Adding the right deletion rule to the relationships ensures the integrity of the model.

I think this will work for you.

class A(object):
    def __init__(self, a, b, c, sum, version='old'):
        self.a = a
        self.b = b
        self.c = c
        self.sum = 6
        self.version = version

    def __int__(self):
        return self.sum + 9000

    def __iter__(self):
        return self.__dict__.iteritems()

a = A(1,2,3,4,5)
print dict(a)

Output

{'a': 1, 'c': 3, 'b': 2, 'sum': 6, 'version': 5}

In Python 3, print is a function, you need to call it like print("hello world").

Alternatively, you can just use,

<li v-for="catalog, key in catalogs">this is index {{++key}}</li>

This is working just fine.

In case of NULL columns it is better to use IF clause like this which combine the two functions of : CONCAT and COALESCE and uses special chars between the columns in result like space or '_'

SELECT FirstName , LastName , 
IF(FirstName IS NULL AND LastName IS NULL, NULL,' _ ',CONCAT(COALESCE(FirstName ,''), COALESCE(LastName ,''))) 
AS Contact_Phone FROM   TABLE1

Save yourself some troubleshooting time and log your require call, like so:

console.log(require('dotenv').config())

You should see an error with more detailed info on the problem.

I am not sure if anyone would take this much pain to test GET and POST calls. I took Python Flask module and wrote a function that does something similar to what @Robert shared.

from flask import Flask, request
app = Flask(__name__)

@app.route('/method', methods=['GET', 'POST'])
@app.route('/method/<wish>', methods=['GET', 'POST'])
def method_used(wish=None):
    if request.method == 'GET':
        if wish:
            if wish in dir(request):
                ans = None
                s = "ans = str(request.%s)" % wish
                exec s
                return ans
            else:
                return 'This wish is not available. The following are the available wishes: %s' % [method for method in dir(request) if '_' not in method]
        else:
            return 'This is just a GET method'
    else:
        return "You are using POST"

When I run this, this follows:

C:\Python27\python.exe E:/Arindam/Projects/Flask_Practice/first.py
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 581-155-269
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Now lets try some calls. I am using the browser.

http://127.0.0.1:5000/method

This is just a GET method

http://127.0.0.1:5000/method/NotCorrect

This wish is not available. The following are the available wishes: ['application', 'args', 'authorization', 'blueprint', 'charset', 'close', 'cookies', 'data', 'date', 'endpoint', 'environ', 'files', 'form', 'headers', 'host', 'json', 'method', 'mimetype', 'module', 'path', 'pragma', 'range', 'referrer', 'scheme', 'shallow', 'stream', 'url', 'values']

Use CASE:

SELECT 
  TABEL1.Id, 
  CASE WHEN EXISTS (SELECT Id FROM TABLE2 WHERE TABLE2.ID = TABLE1.ID)
       THEN 'TRUE' 
       ELSE 'FALSE'
  END AS NewFiled  
FROM TABLE1

If TABLE2.ID is Unique or a Primary Key, you could also use this:

SELECT 
  TABEL1.Id, 
  CASE WHEN TABLE2.ID IS NOT NULL
       THEN 'TRUE' 
       ELSE 'FALSE'
  END AS NewFiled  
FROM TABLE1
  LEFT JOIN Table2
    ON TABLE2.ID = TABLE1.ID

i added

<android.support.v7.widget.Toolbar
...
android:translationZ="5dp"/>

in toolbar description and it works for me. Using 5.0+

I tested the many solutions and finally I came with this solution.

HTML Code

<input type="text" name="UserName" id="UserName" placeholder="UserName" autocomplete="off" />
<input type="text" name="Password" id="Password" placeholder="Password" autocomplete="off"/>

CSS Code

#Password {
    text-security: disc;
    -webkit-text-security: disc;
    -moz-text-security: disc;
}

JavaScript Code

window.onload = function () {
    init();
}

function init() {
    var x = document.getElementsByTagName("input")["Password"];
    var style = window.getComputedStyle(x);
    console.log(style);

    if (style.webkitTextSecurity) {
        // Do nothing
    } else {
        x.setAttribute("type", "password");
    }
}

(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:

GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \ git clone myuser@myGitRemoteServer:/my/remote/git_repo/path

This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

function calc()
{
  if (document.getElementById('xxx').checked) 
  {
      document.getElementById('totalCost').value = 10;
  } else {
      calculate();
  }
}

HTML

<input type="checkbox" id="xxx" name="xxx" onclick="calc();"/>

I created a more comprehensive and cleaner version that some people might find useful for remembering which name corresponds to which value. I used Chrome Dev Tool's color code and labels are organized symmetrically to pick up analogies faster:

• Note 1: clientLeft also includes the width of the vertical scroll bar if the direction of the text is set to right-to-left (since the bar is displayed to the left in that case)

• Note 2: the outermost line represents the closest positioned parent (an element whose position property is set to a value different than static or initial). Thus, if the direct container isn’t a positioned element, then the line doesn’t represent the first container in the hierarchy but another element higher in the hierarchy. If no positioned parent is found, the browser will take the html or body element as reference

Hope somebody finds it useful, just my 2 cents ;)

You could try this:

1. Open the Terminal application. It can be found in the Utilities directory inside the Applications directory.
2. Type the following: echo 'export PATH=YOURPATHHERE:$PATH' >> ~/.profile, replacing "YOURPATHHERE" with the name of the directory you want to add. Make certain that you use ">>" instead of one ">".
3. Hit Enter.
4. Close the Terminal and reopen. Your new Terminal session should now use the new PATH.

Right click on the file on package Explorer Then go to Show in Under it go to terminal Eclipse will have a terminal then Use javac fileName to compile

Those steps should be able to be shortened down to:

hg pull
hg update -r MY_BRANCH -C

The -C flag tells the update command to discard all local changes before updating.

However, this might still leave untracked files in your repository. It sounds like you want to get rid of those as well, so I would use the purge extension for that:

hg pull
hg update -r MY_BRANCH -C
hg purge

In any case, there is no single one command you can ask Mercurial to perform that will do everything you want here, except if you change the process to that "full clone" method that you say you can't do.

Xcode::Install is a simple cli software that allow you to install/select a specific Xcode version.

You can install it using gem install xcode-install
Then you will be able to install a specific version with xcversion install 9.4.1
And if you have more than one version installed, you can switch version with xcversion select 9.4

You can find more information at https://github.com/KrauseFx/xcode-install

Suppose you want to write that in the same file, you can do as follows:

Set-Content -Path "C:\temp\Newtext.txt" -Value (get-content -Path "c:\Temp\Newtext.txt" | Select-String -Pattern 'H\|159' -NotMatch)

If you happen to be using the amqplib library as I am, they have a handy example of an implementation of the Publish/Subscribe RabbitMQ tutorial which you might find handy.

(Posted on behalf of the OP).

I believe I figured it out.

In my case, I added [class*="col-"] {padding: 0 7.5px;};.

Then added .row {margin: 0 -7.5px;}.

This works pretty well, except there is 1px margin on both sides. So I just make .row {margin: 0 -7.5px;} to .row {margin: 0 -8.5px;}, then it works perfectly.

I have no idea why there is a 1px margin. Maybe someone can explain it?

See the sample I created:

Demo
Code

**This can be achived easily using two different ways:**

1)We can also do this by using addClass and removeClass of Jquery
2)Toggle class of jQuery

**1)First Way**

$(documnet.ready(function(){
$('#dvId').click(function(){
  $('#dvId').removeClass('active class or your class name which you want to    remove').addClass('active class or your class name which you want to add');     
});
});

**2) Second Way**

i) Here we need to add the class which we want to show while page get loads.
ii)after clicking on div we we will toggle class i.e. the class is added while loading page gets removed and class which we provide in toggleClss gets added :)

<div id="dvId" class="ActiveClassname ">
</div

$(documnet.ready(function(){
$('#dvId').click(function(){
  $('#dvId').toggleClass('ActiveClassname InActiveClassName');     
});
});


Enjoy.....:)

If you any doubt free to ask any time...

Check your Logcat message and see your Manifest file. There should be something missing like defining the Activity,User permission`, etc.

Actually, you have to explicitly compare it to true. If the dialog doesn't exist yet, it will not return false (as you would expect), it will return a DOM object.

if ($('#mydialog').dialog('isOpen') === true) {
    // true
} else {
    // false
}

import * as express from "express";

This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.

In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.

It's simple please follow the below step.

1. On IntelliJ press 'Ctrl Alt + S' [ press ctrl alt and S together], this will open 'Setting popup'
2. In Search panel 'left top search 'Theme' keyword.
3. In left panel itself you can see 'Appearance', click on this

4. Right side panel you can see Theme: and drop down with following option

   • Dracula
   • IntelliJ
   • Windows

just select which ever you want and click on apply and Ok.

I hope this may work for you..

I misunderstood question. Sorry. for editor - File->Settings->Editor->Colors &Fonts and choose your scheme.... :)

In my case, I copied the curl command from Confluence to TextEdit. After spending almost an hour, and trying to paste the command in different text editors in order to sanitize, finally, PyCharm helped me (IntelliJ should help too)

After pasting it in PyCharm I got to see the error

After removing these "NBSP" (non-breaking spaces), the command started running fine.

There are a couple of ways that you can accomplish this. You can do the following:

<li>
     @Html.ActionLink("Clients", "Index", "User", new { @class = "elements" }, null)
</li>

or this:

<li>
     <a href="@Url.Action("Index", "Users")" class="elements">
          <span>Clients</span>
     </a>
</li>

Lately I do the following:

<a href="@Url.Action("Index", null, new { area = string.Empty, controller = "User" }, Request.Url.Scheme)">
     <span>Clients</span>
</a>

The result would have http://localhost/10000 (or with whatever port you are using) to be appended to the URL structure like:

http://localhost:10000/Users

I hope this helps.

Suppose you want to add an item at a position, then the list size must be more than the position.

add(2, item): this syntax means, move the old item at position 2 to next index and add the item at 2nd position.

If there is no item in 2nd position, then this will not work, It'll throw an exception.

That means if you want to add something in position 2,

your list size must be at least (2 + 1) =3, so the items are available at 0,1,2 Position.

in that way it is ensured that the position 2 is accessed safely and there would be no exception.

Try setting your num_threads inside your omp parallel code, it worked for me. This will give output as 4

#pragma omp parallel
{
   omp_set_num_threads(4);
   int id = omp_get_num_threads();
   #pragma omp for
   for (i = 0:n){foo(A);}
}

printf("Number of threads: %d", id);

When you click on the image you'll get the alert:

<img src="logo1.jpg" onClick='alert("Hello World!")'/>

if this is what you want.

You don't mention what environment you're running in, which makes a big difference because there isn't a pure Python web browser that's capable of rendering HTML.

But if you're using a Mac, I've used webkit2png with great success. If not, as others have pointed out there are plenty of options.

The following method will check if any variable is a string (including variables that do not exist).

const is_string = value => {
  try {
    return typeof value() === 'string';
  } catch (error) {
    return false;
  }
};

let example = 'Hello, world!';

console.log(is_string(() => example)); // true
console.log(is_string(() => variable_doesnt_exist)); // false

Instead of client-side geocoding

geocoder.geocode({
    'address': your_address
  }, function (results, status) {
     if (status == google.maps.GeocoderStatus.OK) {
       var geo_data = results[0];
       // your code ...
   } 
})

I would go to server-side geocoding API

var apikey = YOUR_API_KEY;
var query = 'https://maps.googleapis.com/maps/api/geocode/json?address=' + address + '&key=' + apikey;
$.getJSON(query, function (data) {
  if (data.status === 'OK') { 
    var geo_data = data.results[0];
  } 
})

Centering is one of the biggest issues in CSS. However, some tricks exist:

To center your table horizontally, you can set left and right margin to auto:

<style>
  #test {
    width:100%;
    height:100%;
  }
  table {
    margin: 0 auto; /* or margin: 0 auto 0 auto */
  }
</style>

To center it vertically, the only way is to use javascript:

var tableMarginTop = Math.round( (testHeight - tableHeight) / 2 );
$('table').css('margin-top', tableMarginTop) # with jQuery
$$('table')[0].setStyle('margin-top', tableMarginTop) # with Mootools

No vertical-align:middle is possible as a table is a block and not an inline element.

Edit

Here is a website that sums up CSS centering solutions: http://howtocenterincss.com/

You can't call a PHP function with Javascript, in the same way you can't call arbitrary PHP functions when you load a page (just think of the security implications).

If you need to wrap your code in a function for whatever reason, why don't you either put a function call under the function definition, eg:

function test() {
    // function code
}

test();

Or, use a PHP include:

include 'functions.php'; // functions.php has the test function
test();

Here is yet another one-liner for you:

your_array.sort((a, b) => a.distance === b.distance ? 0 : a.distance > b.distance || -1);

I recently ran into the same problem but the issue wasn't related to tabs and spaces but an odd Unicode character that appeared invisible to the eye in my IDE. Eventually, I isolated the problem and typed out the line exactly as it was and checked the git diff:

If you are able to isolate the line before the reported line and type it out again, you might find that it solves your problem. Won't tell you why it happened in the first place, but it at least gets rid of the issue.

That would work depending on what client.get does when passed undefined as its first parameter.

Something like this would be safer:

app.get('/:key?', function(req, res, next) {
    var key = req.params.key;
    if (!key) {
        next();
        return;
    }
    client.get(key, function(err, reply) {
        if(client.get(reply)) {
            res.redirect(reply);
        }
        else {
            res.render('index', {
                link: null
            });
        }
    });
});

There's no problem in calling next() inside the callback.

According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.

Button endDataSendButton = (Button)findViewById(R.id.end_data_send_button);

Similarly you can get the text view by adding a id to it.

I vote for IB(Interactive Brokers). I've used them in the past as was quite happy. Pinnacle Capital Markets trading also has an API (pcmtrading.com) but I haven't used them.

There are a few things you can look at:

Pre-loading your images
Setting a cache time in an .htaccess file
File size of images and base64 encoding them.

Preloading: http://perishablepress.com/3-ways-preload-images-css-javascript-ajax/

Caching: http://www.askapache.com/htaccess/speed-up-sites-with-htaccess-caching.html

There are a couple different thoughts for base64 encoding, some say that the http requests bog down bandwidth, while others say that the "perceived" loading is better. I'll leave this up in the air.

I had to copy C:\Program Files\Java\jdk1.6.0_26\lib\tools.jar to C:\Program Files\Java\jre6\lib\ext

Thanks anyway.

LEFT JOIN the table to itself, with the join condition worked out so the row matched in the joined version of the table is one row previous, for your particular definition of "previous".

Update: At first I was thinking you would want to keep all rows, with NULLs for the condition where there was no previous row. Reading it again you just want that rows culled, so you should an inner join rather than a left join.

Update:

Newer versions of Sql Server also have the LAG and LEAD Windowing functions that can be used for this, too.

You could try this:

Simply place the code in a style tag in the head of the html file

<style>_x000D_
        .jumbotron {_x000D_
            background: url("http://www.californiafootgolfclub.com/static/img/footgolf-1.jpg") center center / cover no-repeat;_x000D_
        }_x000D_
</style>

or put it in a separate css file as shown below

        .jumbotron {_x000D_
            background: url("http://www.californiafootgolfclub.com/static/img/footgolf-1.jpg") center center / cover no-repeat;_x000D_
        }

use center center to center the image horizontally and vertically. use cover to make the image fill out the jumbotron space and finally no-repeat so that the image is not repeated.

I'm rusty on SQL but I think you could use select as to make your own temporary query columns.

select field1, field2, 'example' as newfield from table1

That would only exist in your query results, of course. You're not actually modifying the table.

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.

To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings ? Display ? Animation) then the dialogs won't be animated no matter what you do!

The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="PauseDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
    </style>

    <style name="PauseDialogAnimation">
        <item name="android:windowEnterAnimation">@anim/spin_in</item>
        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
    </style>

The windowEnterAnimation is one of my animations and is located in res\anim. The windowExitAnimation is one of the animations that is part of the Android SDK.

Then when I create the Dialog in my activities onCreateDialog(int id) method I do the following.

Dialog dialog = new Dialog(this, R.style.PauseDialog);

// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);

Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.

Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;

I am new to XAMPP, but I find that a combination of these suggestions works best (At least on Windows 8.1 with the latest version of XAMPP. Note that the computer I tested this on, also had skype).

First logon to skype and navigate to "Tools < Options < Advanced < Connection." Then check the box that says "Use port 80 and 443 for additional incoming connections." Save, close, and quit skype.

Next, on your XAMPP control panel, click "config < my.ini" and change lines 19 and 27 (should have port = 3306) from "3306" to "3307."

Also, you will need to navigate to xampp < phpMyAdmin < config.inc and change line 27, which should like something like this:

$cfg['Servers'][$i]['host'] = '127.0.0.1';

You will need to add "3307" as follows:

$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

Now, open your browser and you should see the xampp page when you type in "localhost." Additionally, if this is your first time using xampp, you may see a warning about your lack of password (highlighted in pink) on your localhost/phpmyadmin/ page. This is easily remedied by going to the "user accounts" tab in phpmyadmin, clicking on "edit privileges" and entering password. Remember to save the hashed version of any and all passwords you create as we will use this next! -I opened a notepad and saved (and numbered) them. Note that phpMyadmin will notify you of when you are changing the password for your current session (this will be displayed at the top of your phpMyadmin page and is very important, as you will need THAT specific hashed version of your password).

Next, you will need to navigate to the following location "xampp < phpMyAdmin < config.inc" on your computer and open and edit the file with a text editor. You will want to put in the hashed version of your password between the single quotes for password and change "AllowNoPassword" from true to false.

And, that ought to do it.

This is not specific to the question, but this question showed up when I was Googling for the mentioned UnknownHostException, and the fix is not found anywhere else so I thought I'd add an answer here.

The exception that was continuously received was:

java.net.UnknownHostException:  google.com
    at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:184)
    at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392)
    at java.net.Socket.connect(Socket.java:589)
    at java.net.Socket.connect(Socket.java:538)

    at java.net.Socket.<init>(Socket.java:211)
    ... 

No matter how I tried to connect to any valid host, printing it in the terminal would not help either. Everything was right.

The Solution

Not calling trim() for the host string which contained whitespace. In writing a proxy server the host was obtained from HTTP headers with the use of split(":") by semicolons for the HOST header. This left whitespace, and causes the UnknownHostException as a host with whitespace is not a valid host. Doing a host = host.trim() on the String host solved the ambiguous issue.

Notice that this doesn't work in Windows.
The module pxssh does exactly what you want:
For example, to run 'ls -l' and to print the output, you need to do something like that :

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

You shouldn't do string comparisons with ==. That operator will only check to see if it is the same instance, not the same value. Use the .equals method to check for the same value.

if you want your datetime.now() precise till the minute , you can use

datetime.strptime(datetime.now().strftime('%Y-%m-%d %H:%M'), '%Y-%m-%d %H:%M')

similarly for hour it will be

datetime.strptime(datetime.now().strftime('%Y-%m-%d %H'), '%Y-%m-%d %H')

It is kind of a hack, if someone has a better solution, I am all ears

Generically, you can use a custom font using @font-face in your CSS. Here's a very basic example:

@font-face {
    font-family: 'YourFontName'; /*a name to be used later*/
    src: url('http://domain.com/fonts/font.ttf'); /*URL to font*/
}

Then, trivially, to use the font on a specific element:

.classname {
    font-family: 'YourFontName';
}

(.classname is your selector).

Note that certain font-formats don't work on all browsers; you can use fontsquirrel.com's generator to avoid too much effort converting.

You can find a nice set of free web-fonts provided by Google Fonts (also has auto-generated CSS @font-face rules, so you don't have to write your own).

while also preventing people from having free access to download the font, if possible

Nope, it isn't possible to style your text with a custom font embedded via CSS, while preventing people from downloading it. You need to use images, Flash, or the HTML5 Canvas, all of which aren't very practical.

I hope that helped!

This is what worked for me.

check if there exists a typings.json file,

It looks something like this,

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160317120654",
    "jasmine": "registry:dt/jasmine#2.2.0+20160505161446",
    "node": "registry:dt/node#6.0.0+20160613154055"
  }
}

Install typings package globally.

sudo npm install -g typings

after installing typings, run

typings install

then restart the server.

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

I'd say you're only limited by the total amount of RAM available. Obviously the larger the array the longer operations on it will take.

Solution

Using only two lines of CSS, utilizing the magical power of Flexbox

.parent { display: flex; }
.child { margin: auto }

i == 'InvKey' && i == 'PostDate' will never be true, since i can never equal two different things at once.

You're probably trying to write

if (i !== 'InvKey' && i !== 'PostDate')) 

Non-numpy functions like math.abs() or math.log10() don't play nicely with numpy arrays. Just replace the line raising an error with:

m = np.log10(np.abs(x))

Apart from that the np.polyfit() call will not work because it is missing a parameter (and you are not assigning the result for further use anyway).

Run this script from SharePoint 2010 Management Shell as Administrator.

In fact, in R, this operation is very easy:

If the matrix 'a' contains some NaN, you just need to use the following code to replace it by 0:

a <- matrix(c(1, NaN, 2, NaN), ncol=2, nrow=2)
a[is.nan(a)] <- 0
a

If the data frame 'b' contains some NaN, you just need to use the following code to replace it by 0:

#for a data.frame: 
b <- data.frame(c1=c(1, NaN, 2), c2=c(NaN, 2, 7))
b[is.na(b)] <- 0
b

Note the difference is.nan when it's a matrix vs. is.na when it's a data frame.

Doing

#...
b[is.nan(b)] <- 0
#...

yields: Error in is.nan(b) : default method not implemented for type 'list' because b is a data frame.

Note: Edited for small but confusing typos

Paste this function in your Module and use it as like formula

Public Function format_date(t As String)
    format_date = Format(t, "YYYY-MM-DD")
End Function

for example in Cell A1 apply this formula

=format_date(now())

it will return in YYYY-MM-DD format. Change any format (year month date) as your wish.

if((a.trim()=="")||(a=="")||(a==null))
{
    //empty condition
}
else
{
    //working condition
}

There is no way to do this with slf4j.

I imagine that the reason that this functionality is missing is that it is next to impossible to construct a Level type for slf4j that can be efficiently mapped to the Level (or equivalent) type used in all of the possible logging implementations behind the facade. Alternatively, the designers decided that your use-case is too unusual to justify the overheads of supporting it.

Concerning @ripper234's use-case (unit testing), I think the pragmatic solution is modify the unit test(s) to hard-wire knowledge of what logging system is behind the slf4j facade ... when running the unit tests.

Old answer:

Try using this URL: http://translate.google.com/translate_tts?tl=en&q=Hello%20World It will automatically generate a wav file which you can easily get with an HTTP request through any .net programming.

Edit:

Ohh Google, you thought you could prevent people from using your wonderful service with flimsy http header verification.

Here is a solution to get a response in multiple languages (I'll try to add more as we go):

NodeJS

// npm install `request`
const fs = require('fs');
const request = require('request');
const text = 'Hello World';

const options = {
    url: `https://translate.google.com/translate_tts?ie=UTF-8&q=${encodeURIComponent(text)}&tl=en&client=tw-ob`,
    headers: {
        'Referer': 'http://translate.google.com/',
        'User-Agent': 'stagefright/1.2 (Linux;Android 5.0)'
    }
}

request(options)
    .pipe(fs.createWriteStream('tts.mp3'))

Curl

curl 'https://translate.google.com/translate_tts?ie=UTF-8&q=Hello%20Everyone&tl=en&client=tw-ob' -H 'Referer: http://translate.google.com/' -H 'User-Agent: stagefright/1.2 (Linux;Android 5.0)' > google_tts.mp3

Note that the headers are based on @Chris Cirefice's example, if they stop working at some point I'll attempt to recreate conditions for this code to function. All credits for the current headers go to him and the wonderful tool that is WireShark. (also thanks to Google for not patching this)

I used the construction of $.each (data [i], function (key, value) But you must pre-match the names of the selection fields with the names of the form elements. Then, in the loop after "success", autocomplete elements from the "data" array. Did this: autocomplete form with ajax success

IMO, implementation #1 is typical and being short and idiomatic for Perl trumps the others for that alone. A benchmark of the three choices might offer you insight into speed, at least.

In python 3.x all strings are sequences of Unicode characters. and doing the isinstance check for str (which means unicode string by default) should suffice.

isinstance(x, str)

With regards to python 2.x, Most people seem to be using an if statement that has two checks. one for str and one for unicode.

If you want to check if you have a 'string-like' object all with one statement though, you can do the following:

isinstance(x, basestring)

As an alternative to maintain different file if you wiil: If you are using git or any other VCS to push codes from local to server, what you can do is add the settings file to .gitignore.

This will allow you to have different content in both places without any problem. SO on server you can configure an independent version of settings.py and any changes made on the local wont reflect on server and vice versa.

In addition, it will remove the settings.py file from github also, the big fault, which i have seen many newbies doing.

Acknowledging the fact that the asker specifically requested jQuery and that the answer selected is correct, it should be noted that this problem doesn't actually need jQuery per say. If one desires to solve this problem without it, one can simply set the onClick attribute of the checkboxes that he or she wants to add additional functionality to, like so:

HTML:

<form id="myform">
  <input type="checkbox" name="check1" value="check1" onClick="cbChanged(this);">
  <input type="checkbox" name="check2" value="check2" onClick="cbChanged(this);">
</form>

javascript:

function cbChanged(checkboxElem) {
  if (checkboxElem.checked) {
    // Do something special
  } else {
    // Do something else
  }
}

In Rails 3.2 and Rails 4, Benjamin's popular answer has a slightly different syntax.

First in your terminal:

$ rails g migration change_date_format_in_my_table

Then in your migration file:

  def up
   change_column :my_table, :my_column, :datetime
  end

  def down
   change_column :my_table, :my_column, :date

MySQL function NOW() returns the current timestamp. The only way I found for PHP is using the following code.

        $("#show-me").show('slow');
    } else {

These come from the class version. If you try to load something compiled for java 6 in a java 5 runtime you'll get the error, incompatible class version, got 50, expected 49. Or something like that.

See here in byte offset 7 for more info.

Additional info can also be found here.

The reject actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject() the exception value is undefined, hence the "undefined" part in the error that you get.

You do not show the code that uses the promise, but I reckon it is something like this:

var promise = doSth();
promise.then(function() { doSthHere(); });

Try adding an empty failure call, like this:

promise.then(function() { doSthHere(); }, function() {});

This will prevent the error to appear.

However, I would consider calling reject only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.

Bootstrap.yml is the first file loaded when you start spring boot application and application.property is loaded when application starts.

For v2 maps:

At least for me, the signal(SIGSEGV ...) approach mentioned in another answer did not work on Win32 with Visual C++ 2015. What did work for me was to use _set_se_translator() found in eh.h. It works like this:

Step 1) Make sure you enable Yes with SEH Exceptions (/EHa) in Project Properties / C++ / Code Generation / Enable C++ Exceptions, as mentioned in the answer by Volodymyr Frytskyy.

Step 2) Call _set_se_translator(), passing in a function pointer (or lambda) for the new exception translator. It is called a translator because it basically just takes the low-level exception and re-throws it as something easier to catch, such as std::exception:

#include <string>
#include <eh.h>

// Be sure to enable "Yes with SEH Exceptions (/EHa)" in C++ / Code Generation;
_set_se_translator([](unsigned int u, EXCEPTION_POINTERS *pExp) {
    std::string error = "SE Exception: ";
    switch (u) {
    case 0xC0000005:
        error += "Access Violation";
        break;
    default:
        char result[11];
        sprintf_s(result, 11, "0x%08X", u);
        error += result;
    };
    throw std::exception(error.c_str());
});

Step 3) Catch the exception like you normally would:

try{
    MakeAnException();
}
catch(std::exception ex){
    HandleIt();
};

It's simple code to convert that to all lower case.

Not so simple to convert "true" back to "True", however.

true.ToString().ToLower() 

is what I use for xml output.

\n is a line feed (LF) character, character code 10. \r is a carriage return (CR) character, character code 13. What they do differs from system to system. On Windows, for instance, lines in text files are terminated using CR followed immediately by LF (e.g., CRLF). On Unix systems and their derivatives, only LF is used. (Macs prior to Mac OS X used CR, but Mac OS X is a *nix derivative and so uses LF.)

In the old days, LF literally did just a line feed on printers (moving down one line without moving where you are horizonally on the page), and CR similarly moved back to the beginning of the line without moving the paper up, hence some systems (like Windows) sending CR (return to the left-hand side) and LF (and feed the paper up).

Because of all this confusion, some output targets will accept multiple line break sequences, so you could see the same effect from either character depending on what you're outputting to.

if (strtotime($date)>strtotime(0)) { echo 'it is a date' }

this is one of the misunderstood concept in JavaScript because it behaves little differently from place to place. Simply, this refers to the "owner" of the function we are currently executing.

this helps to get the current object (a.k.a. execution context) we work with. If you understand in which object the current function is getting executed, you can understand easily what current this is

var val = "window.val"

var obj = {
    val: "obj.val",
    innerMethod: function () {
        var val = "obj.val.inner",
            func = function () {
                var self = this;
                return self.val;
            };

        return func;
    },
    outerMethod: function(){
        return this.val;
    }
};

//This actually gets executed inside window object 
console.log(obj.innerMethod()()); //returns window.val

//Breakdown in to 2 lines explains this in detail
var _inn = obj.innerMethod();
console.log(_inn()); //returns window.val

console.log(obj.outerMethod()); //returns obj.val

Above we create 3 variables with same name 'val'. One in global context, one inside obj and the other inside innerMethod of obj. JavaScript resolves identifiers within a particular context by going up the scope chain from local go global.

Few places where this can be differentiated

Calling a method of a object

var status = 1;
var helper = {
    status : 2,
    getStatus: function () {
        return this.status;
    }
};

var theStatus1 = helper.getStatus(); //line1
console.log(theStatus1); //2

var theStatus2 = helper.getStatus;
console.log(theStatus2()); //1

When line1 is executed, JavaScript establishes an execution context (EC) for the function call, setting this to the object referenced by whatever came before the last ".". so in the last line you can understand that a() was executed in the global context which is the window.

With Constructor

this can be used to refer to the object being created

function Person(name){
    this.personName = name;
    this.sayHello = function(){
        return "Hello " + this.personName;
    }
}

var person1 = new Person('Scott');
console.log(person1.sayHello()); //Hello Scott

var person2 = new Person('Hugh');
var sayHelloP2 = person2.sayHello;
console.log(sayHelloP2()); //Hello undefined

When new Person() is executed, a completely new object is created. Person is called and its this is set to reference that new object.

Function call

function testFunc() {
    this.name = "Name";
    this.myCustomAttribute = "Custom Attribute";
    return this;
}

var whatIsThis = testFunc();
console.log(whatIsThis); //window

var whatIsThis2 = new testFunc();
console.log(whatIsThis2);  //testFunc() / object

console.log(window.myCustomAttribute); //Custom Attribute 

If we miss new keyword, whatIsThis referes to the most global context it can find(window)

With event handlers

If the event handler is inline, this refers to global object

<script type="application/javascript">
    function click_handler() {
        alert(this); // alerts the window object
    }
</script>

<button id='thebutton' onclick='click_handler()'>Click me!</button>

When adding event handler through JavaScript, this refers to DOM element that generated the event.

• You can also manipulate the context using .apply() .call() and .bind()
• JQuery proxy is another way you can use to make sure this in a function will be the value you desire. (Check Understanding $.proxy(), jQuery.proxy() usage)
• What does var that = this means in JavaScript

I used the answer by @Spenhouet and added more "replacements"-possibilities than "*". For example "?". Just add your needs to the dict in replaceHelper.

/**
 * @param {string} str
 * @param {string} rule
 * checks match a string to a rule
 * Rule allows * as zero to unlimited numbers and ? as zero to one character
 * @returns {boolean}
 */
function matchRule(str, rule) {
  const escapeRegex = (str) => str.replace(/([.*+?^=!:${}()|\[\]\/\\])/g, "\\$1");
  return new RegExp("^" + replaceHelper(rule, {"*": "\\d*", "?": ".?"}, escapeRegex) + "$").test(str);
}

function replaceHelper(input, replace_dict, last_map) {
  if (Object.keys(replace_dict).length === 0) {
    return last_map(input);
  }
  const split_by = Object.keys(replace_dict)[0];
  const replace_with = replace_dict[split_by];
  delete replace_dict[split_by];
  return input.split(split_by).map((next_input) => replaceHelper(next_input, replace_dict, last_map)).join(replace_with);
}

This is a subjective opinion, but I think a text editor shouldn't do everything and the kitchen sink. I prefer lightweight flexible and powerful (in their specialized fields) editors. Although being mostly a Windows user, I like the Unix philosophy of having lot of specialized tools that you can pipe together (like the UnxUtils) rather than a monster doing everything, but not necessarily as you would like it!

Find in files is on the border of these extra features, but useful when you can double-click on a found line to open the file at the right line. Note that initially, in SciTE it was just a Tools call to grep or equivalent!
FTP is very close to off topic, although it can be seen as an extended open/save dialog.
Replace in files is too much IMO: it is dangerous (you can mess lot of files at once) if you have no preview, etc. I would rather use a specialized tool I chose, perhaps among those in Multi line search and replace tool.

To answer the question, looking at N++, I see a Run menu where you can launch any tool, with assignment of a name and shortcut key. I see also Plugins > NppExec, which seems able to launch stuff like sed (not tried it).

if [ ! -z "$var" ] && [ -e "$var" ]; then
      # something ...
fi

you can use generic class:

class Wrapped<T>  {
    private T _value;

    public Action ValueChanged;

    public T Value
    {
        get => _value;

        set
        {
            _value = value;
            OnValueChanged();
        }
    }

    protected virtual void OnValueChanged() => ValueChanged?.Invoke() ;
}

and will be able to do the following:

var i = new Wrapped<int>();

i.ValueChanged += () => { Console.WriteLine("changed!"); };

i.Value = 10;
i.Value = 10;
i.Value = 10;
i.Value = 10;

Console.ReadKey();

result:

changed!
changed!
changed!
changed!
changed!
changed!
changed!

You can use grouping, and get the first car from each group:

List<Car> distinct =
  cars
  .GroupBy(car => car.CarCode)
  .Select(g => g.First())
  .ToList();

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

Differences in In python 2 and 3 version:

If you already have a default method in a class with same name and you re-declare as a same name it will appear as unbound-method call of that class instance when you wanted to instantiated it.

If you wanted class methods, but you declared them as instance methods instead.

An instance method is a method that is used when to create an instance of the class.

An example would be

   def user_group(self):   #This is an instance method
        return "instance method returning group"

Class label method:

   @classmethod
   def user_group(groups):   #This is an class-label method
        return "class method returning group"

In python 2 and 3 version differ the class @classmethod to write in python 3 it automatically get that as a class-label method and don't need to write @classmethod I think this might help you.

I used this simple code to get difference in Years, Months, days with current date.

var sdt = new Date('1972-11-30');
var difdt = new Date(new Date() - sdt);
alert((difdt.toISOString().slice(0, 4) - 1970) + "Y " + (difdt.getMonth()+1) + "M " + difdt.getDate() + "D");

You can write a custom UICollectionView layout to achieve this, here is demo image of my implementation:

Here's code repository: KSTCollectionViewPageHorizontalLayout

@iPhoneDev (this maybe help you too)

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[contains(text(), 'YourTextHere')]")));
assertNotNull(driver.findElement(By.xpath("//*[contains(text(), 'YourTextHere')]")));
String yourButtonName = driver.findElement(By.xpath("//*[contains(text(), 'YourTextHere')]")).getAttribute("innerText");
assertTrue(yourButtonName.equalsIgnoreCase("YourTextHere"));

Oracle stores only the fractions up to second in a DATE field.

Use TIMESTAMP instead:

SELECT  TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM    dual

, possibly casting it to a DATE then:

SELECT  CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM    dual

On cpanel -> software and services -> Select PHP Version.

Choose a PHP version which not the native one (I recommend php 5.6 or last one) and you will have / see a new link "Switch To PHP Settings", click it, in PHP Settings you can set upload_max_filesize in last line , clicking on value ( default is 2M ) , and you got a dropbox with values that you can set to upload_max_filesize, and click save .

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

You should be able to do this by simply typing npm install -g [email protected]. If this does not work, I am beginning to wonder what version of node and npm you are on. Try node -v and npm -v to find these out. You should be on node >4.5 and npm >3

To get the names of current directory we can use getcwd() or dirname(__FILE__) but getcwd() and dirname(__FILE__) are not synonymous. They do exactly what their names are. If your code is running by referring a class in another file which exists in some other directory then these both methods will return different results.

For example if I am calling a class, from where these two functions are invoked and the class exists in some /controller/goodclass.php from /index.php then getcwd() will return '/ and dirname(__FILE__) will return /controller.

This is the same method I have been using for a couple of years now and I haven't seen or found anything better. As people have said, PHP is single threaded, so there isn't much else you can do.

I have actually added one extra level to this and that's getting and storing the process id. This allows me to redirect to another page and have the user sit on that page, using AJAX to check if the process is complete (process id no longer exists). This is useful for cases where the length of the script would cause the browser to timeout, but the user needs to wait for that script to complete before the next step. (In my case it was processing large ZIP files with CSV like files that add up to 30 000 records to the database after which the user needs to confirm some information.)

I have also used a similar process for report generation. I'm not sure I'd use "background processing" for something such as an email, unless there is a real problem with a slow SMTP. Instead I might use a table as a queue and then have a process that runs every minute to send the emails within the queue. You would need to be warry of sending emails twice or other similar problems. I would consider a similar queueing process for other tasks as well.

Another option is to add a single image (not necessarily big) in the drawables (let's name it backgroung.jpg), create an ImageView iv_background at the root of your xml without a "src" attribute. Then in the onCreate method of the corresponding activity:

    /* create a full screen window */
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.your_activity);

    /* adapt the image to the size of the display */
    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point();
    display.getSize(size);
    Bitmap bmp = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(
      getResources(),R.drawable.background),size.x,size.y,true);

    /* fill the background ImageView with the resized image */
    ImageView iv_background = (ImageView) findViewById(R.id.iv_background);
    iv_background.setImageBitmap(bmp);

No cropping, no many different sized images. Hope it helps!

When you use the exec() function, it is as though you have a cmd terminal open and are typing commands straight to it.

Use single quotes like this $str = exec('start /B Path\to\batch.bat');
The /B means the bat will be executed in the background so the rest of the php will continue after running that line, as opposed to $str = exec('start /B /C command', $result); where command is executed and then result is stored for later use.

PS: It works for both Windows and Linux.
More details are here http://www.php.net/manual/en/function.exec.php :)

This is another version which work in case you have some tasks to cleanup. Code will leave clean up process in their method.

package main

import (
    "fmt"
    "os"
    "os/signal"
    "syscall"

)



func main() {

    _,done1:=doSomething1()
    _,done2:=doSomething2()

    //do main thread


    println("wait for finish")
    <-done1
    <-done2
    fmt.Print("clean up done, can exit safely")

}

func doSomething1() (error, chan bool) {
    //do something
    done:=make(chan bool)
    c := make(chan os.Signal, 2)
    signal.Notify(c, os.Interrupt, syscall.SIGTERM)
    go func() {
        <-c
        //cleanup of something1
        done<-true
    }()
    return nil,done
}


func doSomething2() (error, chan bool) {
    //do something
    done:=make(chan bool)
    c := make(chan os.Signal, 2)
    signal.Notify(c, os.Interrupt, syscall.SIGTERM)
    go func() {
        <-c
        //cleanup of something2
        done<-true
    }()
    return nil,done
}

in case you need to clean main function you need to capture signal in main thread using go func() as well.

java.util.MissingResourceException: Can't find bundle for base name
    org.jfree.chart.LocalizationBundle, locale en_US

To the point, the exception message tells in detail that you need to have either of the following files in the classpath:

/org/jfree/chart/LocalizationBundle.properties

or

/org/jfree/chart/LocalizationBundle_en.properties

or

/org/jfree/chart/LocalizationBundle_en_US.properties

Also see the official Java tutorial about resourcebundles for more information.

But as this is actually a 3rd party managed properties file, you shouldn't create one yourself. It should be already available in the JFreeChart JAR file. So ensure that you have it available in the classpath during runtime. Also ensure that you're using the right version, the location of the propertiesfile inside the package tree might have changed per JFreeChart version.

When executing a JAR file, you can use the -cp argument to specify the classpath. E.g.:

java -jar -cp c:/path/to/jfreechart.jar yourfile.jar

Alternatively you can specify the classpath as class-path entry in the JAR's manifest file. You can use in there relative paths which are relative to the JAR file itself. Do not use the %CLASSPATH% environment variable, it's ignored by JAR's and everything else which aren't executed with java.exe without -cp, -classpath and -jar arguments.

I'm not sure I'm repeating someone but some time ago some good soul wrote Y-operator for recursively called function like:

def tail_recursive(func):
  y_operator = (lambda f: (lambda y: y(y))(lambda x: f(lambda *args: lambda: x(x)(*args))))(func)
  def wrap_func_tail(*args):
    out = y_operator(*args)
    while callable(out): out = out()
    return out
  return wrap_func_tail

and then recursive function needs form:

def my_recursive_func(g):
  def wrapped(some_arg, acc):
    if <condition>: return acc
    return g(some_arg, acc)
  return wrapped

# and finally you call it in code

(tail_recursive(my_recursive_func))(some_arg, acc)

for Fibonacci numbers your function looks like this:

def fib(g):
  def wrapped(n_1, n_2, n):
    if n == 0: return n_1
    return g(n_2, n_1 + n_2, n-1)
  return wrapped

print((tail_recursive(fib))(0, 1, 1000000))

output:

..684684301719893411568996526838242546875

(actually tones of digits)

I know this is a super old post, but I think what is missed is overriding __repr__, so that __repr__ = __str__, which is the accepted answer of this question marked duplicate.

In absence of a white-list feature you have to make the "all" or "nothing" Choice. You can disable mixed content blocking completely.

The Nothing Choice

You will need to permanently disable mixed content blocking for the current active profile.

In the "Awesome Bar," type "about:config". If this is your first time you will get the "This might void your warranty!" message.

Yes you will be careful. Yes you promise!

Find security.mixed_content.block_active_content. Set its value to false.

The All Choice

iDevelApp's answer is awesome.

try this:

.button input, .button a {
//css here
}

That will apply the style to all a tags nested inside of <p class="button"></p>

In your Activity.java import android.support.v7.widget.Toolbar instead of android.widget.Toolbar:

import android.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v7.widget.Toolbar;


public class rutaActivity extends AppCompactActivity {

private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ruta);

    getSupportActionBar().hide();//Ocultar ActivityBar anterior

    toolbar = (Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar); //NO PROBLEM !!!!

Update:

If you are using androidx, replace

import android.support.v7.widget.Toolbar;
import android.support.v7.app.AppCompatActivity;

with newer imports

import androidx.appcompat.widget.Toolbar;
import androidx.appcompat.app.AppCompatActivity;

To understand why, you need to know that the CPU represents signed numbers using the two's complement (maybe not all, but many).

    byte n = 1; //0000 0001 =  1
    n = ~n + 1; //1111 1110 + 0000 0001 = 1111 1111 = -1

And also, that the type int and unsigned int can be of different sized depending on your CPU. When doing specific stuff like this:

   #include <stdint.h>
   int8_t ibyte;
   uint8_t ubyte;
   int16_t iword;
   //......

With the new feature WindowInsetsCompat in androidx core release 1.5.0-alpha02 you could check the visibility of the soft keyboard easily as below

Quoting from reddit comment

val View.keyboardIsVisible: Boolean
    get() = WindowInsetsCompat
        .toWindowInsetsCompat(rootWindowInsets)
        .isVisible(WindowInsetsCompat.Type.ime())

Some note about backward compatibility, quoting from release notes

New Features

The WindowInsetsCompat APIs have been updated to those in the platform in Android 11. This includes the new ime() inset type, which allows checking the visibility and size of the on-screen keyboard.

Some caveats about the ime() type, it works very reliably on API 23+ when your Activity is using the adjustResize window soft input mode. If you’re instead using the adjustPan mode, it should work reliably back to API 14.

if you want to execute ENABLE TRIGGER Directly From Source :

we can't write like this:

Conn.Execute "ENABLE TRIGGER trigger_name ON table_name"

instead, we can write :

Conn.Execute "ALTER TABLE table_name DISABLE TRIGGER trigger_name"

Arrays:

{{#each array}}
    {{@index}}: {{this}}
{{/each}}

If you have arrays of objects... you can iterate through the children:

{{#each array}}
    //each this = { key: value, key: value, ...}
    {{#each this}}
        //each key=@key and value=this of child object 
        {{@key}}: {{this}}
        //Or get index number of parent array looping
        {{@../index}}
    {{/each}}
{{/each}}

Objects:

{{#each object}}
    {{@key}}: {{this}}
{{/each}} 

If you have nested objects you can access the key of parent object with {{@../key}}

Just a small correction to the first answer in this thread.

Even for Stack, you need to create new object with generics if you are using Stack from java util packages.

Right usage:
    Stack<Integer> s = new Stack<Integer>();
    Stack<String> s1 = new Stack<String>();

    s.push(7);
    s.push(50);

    s1.push("string");
    s1.push("stack");

if used otherwise, as mentioned in above post, which is:

    /*
    Stack myStack = new Stack();
    // add any type of elements (String, int, etc..)
    myStack.push("Hello");
    myStack.push(1);
    */

Although this code works fine, has unsafe or unchecked operations which results in error.

Yes Jython does this, but it may or may not be what you want

So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.

One way I solved this problem was by making the beginning of the path relative. For your case:

gulp.src([
    'index.php',
    '*css/**/*',
    '*js/**/*',
    '*src/**/*',
])
.pipe(gulp.dest('/var/www/'));

The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)

This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/ at the same level as js, you would end up matching both.

This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.

You can link to file, but not to folders, and keep in mind that, Github will add /blob/master/ before your relative link(and folders lacks that part so they cannot be linked, neither with HTML <a> tags or Markdown link).

So, if we have a file in myrepo/src/Test.java, it will have a url like:

https://github.com/WesternGun/myrepo/blob/master/src/Test.java

And to link it in the readme file, we can use:

[This is a link](src/Test.java)

or: <a href="src/Test.java">This is a link</a>.

(I guess, master represents the master branch and it differs when the file is in another branch.)

Hive has a lot of good date parsing UDFs: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-DateFunctions

Just doing the string comparison as Nigel Tufnel suggests is probably the easiest solution, although technically it's unsafe. But you probably don't need to worry about that unless your tables have historical data about the medieval ages (dates with only 3 year digits) or dates from scifi novels (dates with more than 4 year digits).

Anyway, if you ever find yourself in a situation where you would want to do fancier date comparisons, or if your date format is not in a "biggest to smallest" order, e.g. the American convention of "mm/dd/yyyy", then you could use unix_timestamp with two arguments:

select *
from your_table
where unix_timestamp(your_date_column, 'yyyy-MM-dd') >= unix_timestamp('2010-09-01', 'yyyy-MM-dd')
and unix_timestamp(your_date_column, 'yyyy-MM-dd') <= unix_timestamp('2013-08-31', 'yyyy-MM-dd')

A self-made solution:

bool isNumeric(const char *str) 
{
    while(*str != '\0')
    {
        if(*str < '0' || *str > '9')
            return false;
        str++;
    }
    return true;
}

Note that this solution should not be used in production-code, because it has severe limitations. But I like it for understanding C-Strings and ASCII.

Both ways are viable, but they do different things when it comes to inheritance with an overridden static method. Choose the one whose behavior you expect:

class Super {
  static whoami() {
    return "Super";
  }
  lognameA() {
    console.log(Super.whoami());
  }
  lognameB() {
    console.log(this.constructor.whoami());
  }
}
class Sub extends Super {
  static whoami() {
    return "Sub";
  }
}
new Sub().lognameA(); // Super
new Sub().lognameB(); // Sub

Referring to the static property via the class will be actually static and constantly give the same value. Using this.constructor instead will use dynamic dispatch and refer to the class of the current instance, where the static property might have the inherited value but could also be overridden.

This matches the behavior of Python, where you can choose to refer to static properties either via the class name or the instance self.

If you expect static properties not to be overridden (and always refer to the one of the current class), like in Java, use the explicit reference.

The below code worked for me :)

window.open('your current page URL', '_self', '');
window.close();

If you are unsure whether your IP address is contained in the above list use an CIDR calculator like http://www.subnet-calculator.com/cidr.php to show the valid IP range.

E. g. for 140.82.112.0/20 the IP range is 140.82.112.0 - 140.82.127.255

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

cd "C:\Users\MyComputer\Documents\Visual Studio 2019\Projects"
